testsuite fixes for bleeding edge gcc

[Zack Weinberg <zack at codesourcery dot com>]

Current development versions of GCC are substantially pickier about
"built-in" library functions being properly declared, which causes a
large number of GDB testsuite failures.

The appended patch adds all the missing declarations to the 6.2-branch
version of the testsuite.  I haven't tried mainline.  Thoughts?
