064360e667 Remove libgcc dependency. 
libgcc for boot environment isn't always present and compatible.
libgcc is often absent if endianness or bit-size at boot is different
from running OS.
libgcc may use optimised opcodes that aren't available on boot time.
So instead of relying on libgcc shipped with the compiler, supply
the functions in GRUB directly.
Tests are present to ensure that those replacement functions behave the
way compiler expects them to.

6a4ecd276e mips: Fix soft-float handling. 
Add -msoft-float alongside clang arguments to specify ABI.
Specify ABI in asm files explicitly.
This trigers asm warning due to gcc failing to propagate -msoft-float
but it's tolerable.

5c066a81c2 Apple assembly doesn't handle symbol arithmetic well. So define an 
offset symbol in boot.S and use it.

78f961efe9 Apple assembly doesn't handle symbol arithmetic well. So instead 
of getting addres of kernel_sector + 4 define kernel_sector_high.
	It also makes code more readable.

09bc0a577d With Apple assembly in .macro environvemnt you have to use $$ instead 
of $. So introduce new preprocessor macro MACRO_DOLLAR(x) which expands
	to $$x on Apple and to $x on everything else.
