[SPARC]: Fix weak aliases
sparc_ksyms.c used to declare weak alias to several gcc intrinsics. It doesn't work with gcc4 anymore - it wants a declaration for the thing we are aliasing to and that's not going to happen for something like .mul, etc. Replaced with direct injection of weak alias on the assembler level - .weak <alias> followed by <alias> = <aliased>; that works on all gcc versions.
