Import various libgcc functions from syslinux.
...
Experimentation reveals that gcc ignores -mrtd for the implicit
arithmetic functions (e.g. __udivdi3), but not for the implicit
memcpy() and memset() functions. Mark the implicit arithmetic
functions with __attribute__((cdecl)) to compensate for this.
(Note: we cannot mark with with __cdecl, because we define __cdecl to
incorporate regparm(0) as well.)

Don't trash the %ecx value returned by relocate(). This was causing

us to round down the size for the relocation copy to the nearest 64kB
