commit: http://git.uclibc.org/uClibc/commit/?id=5e22e71adfef5ad46119cea98fccf4ae998ad0d8
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master
Remove ucontext.h if SUSV4_LEGACY is not set and fix it's references.
Guard sigstack structure with SUSV4_LEGACY and STRICT_HEADERS.
Disable sigstack function prototype, it is not provided by uClibc.
