Do the required flags from pkg-config eventually end up in CFLAGS at the
end of configure?  If they do then this sounds like simply an ordering
problem -- the code that runs pkg-config and modifies CFLAGS should run
before this AC_COMPILE_IFELSE.  If they don't, then that's a separate
problem that is unrelated to and should be solved outside of
AC_COMPILE_IFELSE.  In other words, the macro uses the current setting
of CFLAGS; if CFLAGS needs things added to it, then it should be done
before calling the macro.
