Vladimir Serbinenko 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.

Vladimir Serbinenko f034fab620 Supply signed division to fix ARM compilation.
Previously we supplied only unsigned divisions on platforms that need software
division.
Yet compiler may itself use a signed division. A typical example would be a
difference between 2 pointers which involves division by object size.

Vladimir Serbinenko 252a289cb3 Determine the need for mingw-related stubs at compile time rather than
using not very significant $target_os.

Vladimir Serbinenko 2d76b4d81e Eliminate variable length arrays in grub_vsnprintf_real.
A bit tricky because this function has to continue to work without
	heap for short strings. Fixing prealloc to 32 arguments is reasonable
	but make all stack references use 32-bit offset rather than 8-bit one.
	So split va_args preparsing to separate function and put the prealloc
	into the caller.

Vladimir Serbinenko 4a0aaad022 clang emits calls to abort () under some unknown conditions.
Export abort () when compiling with clang.

Vladimir Serbinenko 6fcec43954 Replace libgcc version of ctz with our own.
On upcoming arm64 port libgcc ctz* are not usable in standalone
	environment. Since we need ctz* for this case and implementation is
	in C we may as well use it on all concerned platforms.
