Patch - Add restrict to sys/time.h

[Joel Sherrill]

There is a typo in this patch. See v2 attached.
Is v2 OK to commit?

And .. v1 accidentally changed _gettimeofday to
gettimeofday in the prototype. Which makes me
ask if the system call _gettimeofday should
have restrict added?

It appears in 44 files in libgloss and libc
if that helps the decision.
