configure: Add option --enable-Werror to add -Werror to CFLAGS.
-Werror is useful for development, but it screws up configure because it's
impossible to guess what new warnings compilers will add in the future.
This commit adds a new configure option to add CFLAGS after the configure
checks are done.
The use of AC_CONFIG_COMMANDS_PRE is based on Eric Blake's suggestion on
the autoconf mailing list: "AC_CONFIG_COMMANDS_PRE probably fits the bill
as the ideal macro to use for guaranteeing that you inject your shell code
at the last possible moment."
