configure: Work around bug in autoconf 2.64 

In autoconf 2.64, if AC_CHECK_LIB is first used in a conditional that
evaluates to false, the helper function ac_fn_c_try_link gets defined
inside that conditional, and then subsequent attempts to use
ac_fn_c_try_link() will blow up.  Work around this by moving an
unconditional use of AC_CHECK_LIB to the beginning of configure.in.
