Compiling the sparc build of upstream kernel generates lots of warnings
regarding version generation failure for functions defined in assembly files.
This can be easily suppressed by adding those function prototypes to
asm/asm-prototypes.h as in powerpc architecture. The following series of patches
aims to clean the following warnings.
WARNING: EXPORT symbol "atomic_add" [vmlinux] version generation failed, symbol will
not be versioned.

Adding asm-prototypes.h for genksyms to generate crc
sed regex in Makefile.build requires line break between exported
