The flag handling (both compiler options and include paths) are a mess at
the moment.  There is no point in forcing "-O2 -g" when these are already
the defaults, and if someone changes the defaults, chances are good they
don't want you clobbering their choices.

The -Wall flag should be handled in configure and thrown into CFLAGS once
rather than every Makefile.am.  Plus, this way we can control which
compilers the flag actually gets used with.

Finally, the INCLUDES variable is for -I paths, not AM_CFLAGS.  Nor should
it contain -I. as this is already in the default includes setup.

Newer automakes error out due to per-file CFLAGS being used unless the
macro AM_PROG_CC_C_O is set in configure.ac.

[jes: The macro AM_PROG_CC_C_O has been around since 1999, so it should
 be safe.]

If any autotool command fails, we want to abort, not keep running.
Otherwise, errors in say a Makefile.am will be missed as the automake
failure gets ignored and then lost in the noise.
