so, I looked into this a bit further. If I change the AIX xlc section of
shlib.conf as follows:

SHLIBVEXT='.a.$(LIBMAJOR).$(LIBMINOR)'
SHLIBEXT=.a

builds fail when trying to build the db2 kdb plugin(make complains of no
rule to create db2.so). If I then change the value of SO_EXT in
plugins/kdb/db2/Makefile.in to .a the build completes but when I run
kdb5_util it can't find the plugin. if I then rename the plugin to
.so(or no extension at all) kdb5_util runs as expected.

so, my question is, if we were to revert the -rtl patches, would it make
more sense to make the plugin code look for .a files as well as .so
files, or would it be preferable to add rules to generate .so files for
plugins even though normal linking on AIX expects .a files unless you
are doing run-time linking.
