This is likely not an automake issue, but may or may not be one with
autoconf.  You are probably more likely to receive useful answers if you
ask this question on the autoconf list, and also provide the exact error
that gcc outputs, plus the config.log parts that correspond to these
tests:

I'm sorry I can't help you any further.
