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.

This will allow building of external components and linking
them at the end of the build process to the main kernel.
add a Makefile.app to the project directory with the required
targets, for example
Makefile.app:
KBUILD_ZEPHYR_APP := /tmp/libapp.a
/tmp/libapp.a:
@touch /tmp/libapp.a

The way we build the libc files is not a real library that can be
used as a libc and makes managing the source files a bit
difficult, so lets revert back to building the c function files
like everything else in the system to avoid any confusion.

See

for more details.
• Support IA32 without FPU.
• Minimum ISA: Pentium ISA without x87 FPU instructions.
• Don't allow mixing i386 object files with Intel MCU object files.
• Support floating point with software emulation:
a. Long double is the same as double.
b. Use __float80 for 80-bit double.
• Minimize memory footprint:
a. Code size
b. Data size
c. Stack size
Here is the draft of Intel MCU psABI. The differences from IA32
psABI are
1. The minimum instruction set is Intel Pentium ISA minus instructions
for x87 floating point unit.
2. There are no x87 floating point registers.
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
general purpose registers.
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__

This introduces a new option
CONFIG_KERNEL_BIN_NAME
that can be used in the kernel configuration (kconfig) to set
the final binary name, for example you can set:
CONFIG_KERNEL_BIN_NAME="test_app"
in the project.conf and this will result in
test_app.{elf,bin} in outdir.
The default is still using the type of the kernel being used, i.e.
microkernel.elf or nanokernel.elf

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.
