The patch below fixes this failure:

../../libtool-master/tests/localization.at:43: (LANG=de_DE LANGUAGE=de_DE 
LC_ALL=de_DE $CC $CPPFLAGS $CFLAGS -c a.c) || exit 1

I think somebody more experienced with darwin needs to look at the other
remaining failure in above log:

    tests: avoid localization failure due to unstable compiler messages.

    * tests/testsuite.at (LT_AT_NORMALIZE_COMPILER_OUTPUT):
    Attempt to normalize temporary file names in error messages.
    Fixes 'localized compiler messages' test failure on Darwin when
    creating fat (multi-ABI) libraries.
