C99 gprof configury

[Alan Modra]

This series of patches is a first pass at tidying some of the obsolete
configure tests we have in support of old systems.  No doubt there are
other things that could be removed too.

Given C99 we don't need to check HAVE_SETLOCALE.  The patch also
adds setitimer checks so that they can be removed from bfd where they
aren't needed.  According to the automake manual AC_ISC_POSIX is
obsolete, so that is removed.  HAVE_SETMODE isn't checked anywhere,
so it is pointless to have a configure test for setmode.

	* configure.ac: Check for sys/time.h and setitimer.  Don't invoke
	AC_ISC_POSIX.  Don't check for setmode.
	* gprof.c: Don't test HAVE_SETLOCALE.
	* gprof.h: Include sys/time.h.
	* configure: Regenerate.
	* gconfig.in: Regenerate.
