libgomp and libatomic might be in use during the build. Thus, ar commands
will failed to add new objetcs to it as the file is considered busy.
Deleting it and recreating it with both architectures fixes that.

This solution doesn't really appeal to me, but there aren't any good options.
AIX caches shared objects in memory for faster startup. If the
archive file permissions do not include read-other (world readable),
the shared object is not cached. But using this option might cause
permission problems at installation. One would need to juggle file
permissions during the build.
The AIX slibclean command will clear all cached shared objects, but it
requires root privileges and is a global action.

It also is confusing for the patch to perform
$(ARX) -X32_64
when immediately before the fragment created ARX by explicitly
stripping -X32_64. If it's going to perform
ar -X32_64
it should use the normal $(AR) variable.
Thanks, David
