The build process of libquadmath sometimes encounters problems on AIX
due to multilib and LD_LIBRARY_PATH interfering with GCC's own library
dependencies.  Libquadmath is not used on AIX, so this patch adds it
to noconfigdirs.

Thanks, David

        * configure.ac: Add libquadmath to noconfigdirs for AIX.
        * configure: Rebuild.

Please include this explanation in a comment on the powerpc-*-aix* | 
rs6000-*-aix* case.  Existing directory-disabling cases may be 
uncommented, but new ones ought to have comments explaining the reason for 
disabling the library.
