For some strange reason IAMCU sets e_machine to 0x06 which causes
QEMU to freak out. This is just x86 code with a different C
calling convention, hack it back to 0x03 (EM_386) before running

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.

3. There are no vector registers.
4. Segment registers are optional.
5. Support for TLS relocations are optional.
6. Scalar types larger than 4 bytes are aligned to 4 bytes.
7. There are no vector types.
8. _Decimal32, _Decimal64, and _Decimal128 types are optional.
9. long double type is the same as double.
10. float, double and long double types are passed and returned in

11. _Decimal32 and _Decimal64 types are passed in general purpose
registers.
12. Aggregate types no larger than 8 bytes are passed and returned
in general purpose registers.
13. Stack is 4-byte aligned.
14. The auxiliary vector support is optional.
15. Register %edx has undefined value at process entry.
16. New ELF machine code: EM_IAMCU.
17. New predefined C/C++ pre-processor symbols: __iamcu and __iamcu__

The kernel version has been converted from a string to a four-byte
quantity that is divided into two parts.
Part 1: The three most significant bytes represent the kernel's
numeric version, x.y.z. These fields denote:
x -- major release
y -- minor release
z -- patchlevel release
Each of these elements must therefore be in the range 0 to 256, inclusive.
Part 2: The least significant byte is reserved for future use.
EXTRAVERSION is used for intermediate releases and customised
builds on top of an existing/released version.

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.
