configure.ac: Use AC_TRY_COMPILE instead of AC_TRY_RUN to check for _POSIX_TIMER...

Original commit message from CVS:
* configure.ac:
Use AC_TRY_COMPILE instead of AC_TRY_RUN to check for
_POSIX_TIMER, _POSIX_MONOTONIC_CLOCK, etc. Makes configure
not fail when trying to crosscompile on OpenEmbedded (#511750).
