Xen devel - Dec 2012 - [PATCH] qemu-traditional: update configure check for -lrt changes in glibc 2.17

configure uses clock_gettime to check whether -lrt is needed - and
don''t
check other functions. With glibc 2.17 clock_gettime is part of libc, so
use timer_gettime instead, which is in -lrt in old and new versions of
glibc.
