Hello,

the attached patch fixes ldso compilation on sparc-linux (at least with
sparc32 userland). It was made against uClibc 0.9.21, but it's still OK
with 0.9.26.

There were three problems:
- missing __NR_getpid definition
- conflicting prototypes in elfinterp.c
- syntax error (missing semicolon) in ldso.c

With this patch shared libraries and ldso can be built on sparc.

It contains also ldso.c syntax fix for m68k - there was the same
mistake two lines earlier; but I didn't test build on m68k.
