The build system uses absolute path names to generate
target names. In Windows, absolute path names include the
character ":".
Makefile does not support target names with the character ":"
on them.
The target names involved are PHONY. The commit modifies the
Makefile logic to not include directory names in zephyr-app-dirs
and clean-dirs targets.

Several Zephyr SDK toolchains support multilibs.
Instead of hard-coding locations of the libraries, the proper/cleanest way
is to query the GCC compiler for the locations of libgcc and libc.
However, in order to do this, we need to ensure a certain order of
initialization in the Makefile:
1. Determine CROSS_COMPILE.
We cannot determine LIB_INCLUDE_DIR, TOOLCHAIN_CFLAGS yet, as we don't
know the KBUILD_CFLAGS yet.
2. Calculate KBUILD_CFLAGS using CROSS_COMPILE
KBUILD_CFLAGS often need the compiler to validate options, i.e:
KBUILD_CFLAGS += $(call cc-option,-mabi=aapcs -mthumb -mcpu=cortex-m0)
However, LIB_INCLUDE_DIR, TOOLCHAIN_CFLAGS should not be needed for this
3. Finally, using CROSS_COMPILE and KBUILD_CFLAGS determine LIB_INCLUDE_DIR,
TOOLCHAIN_CFLAGS by querying GCC using -print-libgcc-file-name and
-print-multi-directory command line options.
This change should only affect Zephyr SDK toolchains, all other toolchains
are expected to function as before.

sections for declaring entires in the sw_isr_table array. It's
imperative that arch/built-in.o be linked after everything else

Currently, any interrupt handlers defined in ext/ or usb/ will not

The -nostdinc flag to GCC makes it not include its own directories when
searching headers, which means they need to be added manually. The same
Makefile line (~657) that adds the -nostdinc is also adding the correct path
for the gcc used to build, using the "-print-file-name=include" switch to get
the correct path for the respective gcc version.
The problem is that including limits.h from newlib will try to include gcc's
version too, which in every toolchain the SDK provides (and at least on my
machine, the same thing applies for the system gcc), limits.h is found under
gcc's "include-fixed" directory, not just include. So another -isystem should
be added with the value from "-print-file-name=include-fixed".

Static interrupts rely on a trick where the _sw_isr_table array
is declared with each element in a different .gnu.linkonce
section, initially pointing to the spurious IRQ handler.
When drivers or apps declare their own interrupts, they override
the element with their own containing the real ISR and parameter.
However, this only works if the initial declaration of the
_sw_isr_table array with the spurious handlers is linked last.
App-specific code was being linked later than the core code,
causing static interrupts declared in apps not to be installed
correctly.
If the _sw_isr_table is moved from SOC-specific code to core arch
code, interrupts configured under soc/ should still also work.

When QEMU loads a multiboot image based on the ELF headers, it
calculates the total memory size subtracting the minimum address from
the maximum address in the program header.
While the IDT section is removed from the ELF, an empty segment in the
program header is still kept at IDT_LIST base address. Since the IDT
segment isn't contiguous with the loadable code segment, QEMU is tricked
into thinking the total memory size is larger than it really is.
To workaround this, change the address of the IDT section to the address
of the text section. This will make objcopy remove the extra segment
entirely when the IDT section is removed.
This could have been fixed in QEMU since this isn't a bug in Zephyr
per-se, but it will be easier to avoid specific QEMU versions
requirements.

Clang support already existed in the Makefiles but was not complete
and some gcc options did not work with clang. Move those to be conditional
on the compiler used to make clang work.
To build with clang for x86:
make CC=clang -C samples/microkernel/apps/hello_world/
You still need the gcc cross environment for various tools.
For now, only x86 was tested.

This change will allow the use of a custom linker script by
setting the config variable CUSTOM_LINKER_SCRIPT to a path outside
of Zephyr tree.
This is useful when an application needs to add sections into the
linker script and avoid having to change the script provided by
Zephyr.

Follow the model of the Linux kernel for adding arch
specific CFLAGS by using the Makefile and Kbuild combination
in the arch/<arch> directory.
This will also allow adding architecture specific targets and is
easy to maintain when alongside the architecture.

Using nm and sed works fine on Linux, however when moving to other
platforms, nm and sed do not work the same way and might have
different behaviour. This reduces dependency on host tools and brings
back the code for generating the offsets.h directly using a built
utility that is portable.
