[patch] override sloppy ltconfig exeext test

[Lars J. Aas]

I suggested this one before, but there was never any comments, so
here's a more "official" submittal...  I know it's kind of "the wrong
fix", but a right fix won't help with the latest released libtool,
and a new libtool release can be some time off...

        * aclang.m4 (_AC_COMPILER_EXEEXT_*): export ac_cv_exeext
        so ltconfig believes the value is cached and skips its own
        faulty test.
