[PATCH] Remove AC_CONFIG_AUX_DIR

[Earnestly]

This patch removed the AC_CONFIG_AUX_DIR definition in configure.ac as
when attempting to run ./configure after autoreconf -fi (which is
recommended over autogen.sh/bootstrap.sh-like scripts[0]) I get the
following error:

configure.ac:73: error: required file 'autoconf/ltmain.sh' not found

For some reason autoreconf -fi was not moving ltmain.sh to the autoconf
directory, so I ended up manually moving ltmain.sh every build.

Looking at other projects such as mpfr I noticed they didn't bother with
the AUX_DIR so I replicated it here and it allows ./configure to succeed
without any intervention.
