Modified Files:
        src/lib/libc/arch/sparc64/gen: resumecontext.c

Log Message:
Pull over rev. 1.5 of the i386 version (../../i386/resumecontext.S),
quoting Matthias Drochner:

> -check for a NULL uc_link before calling setcontext(2); do a real exit(3)
>  instead with exit handlers and all that
> -If setcontext(2) returns (which it shouldn't), do an _exit(-1) rather
>  than relying on a sensible return value to use as exit code. Makes
>  it less likely that an ucontext corruption goes unnoticed.

This also fixes regress/lib/libc/context for sparc64.
