Revert "configure: Fix --enable-XX-bit flags by moving LT_INIT where it should"

This reverts commit 2af28040d639dddbb7c258981a00eaf3dfcbcf03.

The commit was resolving an issue where libtool will not setup the
environment correctly when one explicitly provides --enable-{32,64}-bit
at configure time. It was caused due to the "-m32,64" C{,XX}FLAGS being
set too late relative to LT_INIT.

At the same time this cases the enable_static to be incorrectly set,
amongst others leading to build issues. Rather than being smart and
trying to handle 32/64 bit build ourselves it may be better to delegate
it to the builder/maintainer. The latter should now know better which is
the correct(most appropriate) method.
