Also assume AC_LINK_IFELSE() is OK when cross-compiling for the libs

Wed Dec 11 15:52:01 2002  Owen Taylor  <otaylor@redhat.com>

        * configure.in: Also assume AC_LINK_IFELSE() is
        OK when cross-compiling for the libs checks, and for
        the sched_get_priority_min() check.

        * configure.in: Add cached value glib_cv_use_pid_surrogate.
