The constraints in the inline assembler implementation of i386
strrchr() were incorrect and break the build with recent gcc 4.3.
Since there are only very few callers of strrchr() and none of them
are performance relevant just remove the assembler implementation
and use the C fallback instead.

The compiler generally generates reasonable inline code for the simple
cases and for the rest it's better for code size for them to be out of line.
Also there they can be potentially optimized more in the future.
In fact they probably should be in a .S file because they're all pure
assembly, but that's for another day.
Also some code style cleanup on them while I was on it (this seems
to be the last untouched really early Linux code)
This saves ~12k text for a defconfig kernel with gcc 4.1.
