 uncommented, but new ones ought to have comments explaining the reason for
 disabling the library.

Is the following okay?

Thanks, David

[PATCH] PR bootstrap/52623 Disable libquadmath on AIX

[David Edelsohn]

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.
