Relying on GNU makeisms has automake -Werror fail

Relying on GNU makeisms has "automake -Werror" fail due to the warnings
about GNU makeisms being converted to errors.

Unfortunately, erlusb/Makefile.am is heavily relying on a significant
number of GNU makeisms, so we remove the "-Werror" argument from the
list of automake arguments.

Closes #1.
