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.
