add support for AIX 6.1

[Ralf Wildenhues]

Hello,

OK to apply to HEAD and backport to branch-1-5?  I think we would do
well expecting AIX 7 and 8 and 9 to behave like current, don't you
think?

Rainer, or anybody else with access to AIX 6: if you can test Libtool
CVS HEAD, could you post the output of
  gmake -k check VERBOSE=yes

with the patch below applied, and libltdl/config/config.guess adjusted?

An analogous patch has been sent to <address@hidden>.

Thanks,
Ralf

        Support AIX 6.1.
        * libltdl/m4/libtool.m4 (_LT_SYS_DYNAMIC_LINKER)
        (_LT_CHECK_MAGIC_METHOD, _LT_COMPILER_PIC, _LT_LINKER_SHLIBS)
        (_LT_LANG_C_CONFIG, _LT_LANG_CXX_CONFIG, _LT_LANG_F77_CONFIG)
        (_LT_LANG_FC_CONFIG): Adjust case patterns to match AIX 6
        through 9 as well.
        * libltdl/m4/ltdl.m4 (LT_SYS_DLOPEN_DEPLIBS): Likewise.
