travis: for linux clang builds, use -Werror

Somehow, autoconf thinks that the gcc in the Ubuntu "precise" image that we use in Travis builds does not support C99 (i.e., the AC_PROG_CC_C99 test comes back with "unsupported"). Hence, when we use C99 constructs without the --std=c99 flag on the command line, it results in a warning, and therefore -Werror fails. Hence, we only use -Werror with clang on Linux.
