Ok, with the attached patch:
$ LDFLAGS="-brtl" CC=xlc ./configure
$ LDFLAGS="-brtl" CC=xlc gmake MAKE=gmake check
passes all tests for MLB.
Dan and Robert, please review. The patch does the following:
1. If using runtime-linking, created shared libraries with
-G as the final option. Remove -bM:SRE if runtime-linking
in effect and creating shared libraries.
2. If using runtime-linking, create static libraries *only*
under lib<name>.a and shared libraries *only* under
lib<name>.so.
3. Fix bug in allow_undefined_flag WRT evaluation of
allow_undefined_flag.
4. Rename lt_cv_prog_cc_static to ac_cv_prog_cc_static.
5. Set ac_cv_prog_cc_wl='-Wl,' to fix bug in quote.test.
6. Set soname_spec='${libname}${release}.so$major' to sync
with 1.4.
