Include @DEFS@ into our compiler call

On most systems, this should only result in some useless defines being added to
the compiler's command line:

-DPACKAGE_NAME=\"znc\" -DPACKAGE_TARNAME=\"znc\" -DPACKAGE_VERSION=\"0.097\"
-DPACKAGE_STRING=\"znc\ 0.097\" -DPACKAGE_BUGREPORT=\"\" -DPACKAGE_URL=\"\"

However, on some weird arches like e.g. x86, this will make AC_SYS_LARGEFILE
actually work, because that macro adds "-D_FILE_OFFSET_BITS=64" to @DEPS@.

This was found by SilverLeo because modpython didn't compile for him, thanks. :)
(python has "#define _FILE_OFFSET_BITS 64" in pyconfig.h)
