Right now we are building minimal libc as an archive (lib.a)
and do not need to link against -lc -lm in that case.
Link against libc/libm only when using an external libc.

This commit adds the variable LDLIBS_TOOLCHAIN that, by default,
add the gcc static library to the link command.
This variable can be overriden as an environmental variable or as a make
parameter to allow the use of different toolchains different from gcc.

This commit allows the following:
lib-y will create external directories, when building with
the O=<external/directory>option.
Originally in Kbuild, only obj-y dependencies were subject to
directory creation when builded in an external directory.
This change allow Kbuild to completely build in external
directories, including libc.a.

This commit changes the way libc is built.
Instead of building a hierarchy of objects linked into the
microkernel, libc minimal is built as a static library and
linked against the microkernel binary.
The location of the libc is configurable with the variable
KLIBC_DIR. This gives the flexibility to build against a
different libc other than minimal.

This commit fixes issues to allow build on ARM architecture.
- It fixes the include paths in Makefiles.
- It fixes the include path for the offsets.c compilation.
- It fixes the linker command. This changes is needed because gcc
ARM cross-compiler does not accept an AT() command without
specifing an address explicitly. This corner case appears
on ARM architectures when XIP is disabled.

This commit removes the Kconfig symbol KERNEL_DIR.
The symbols was no longer needed because sysgen is only
used on microkernel architectures and the value of
KERNEL_DIR is always "ukernel", therefore it is redundant.

This commit substitutes references to the linux string in variable

It changes the LINUX prefix and uses the TIMO prefix (short for

It changes the vmlinux prefix for tinymountain prefix.
It preserves linux references found in licenses, comments giving
credits and from scripts that are not supported by the current build
system yet, like rpm generation.
