[git commit master] sh: Add a prototype for the gcc __set_fpscr internal function

[Carmelo Amoroso]

commit: http://git.uclibc.org/uClibc/commit/?id=c5c2cf0da5644c96a2ae3db315f51bf91f15723d
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master

The sh port uses the gcc __set_fpscr internal function, but neither gcc
nor glibc creates a prototype for it.  This leads to a bunch of random
warnings about implicit decls during the build.
