Now that GNAT supports multilib configurations, it is possible to build a
32-bit Ada compiler on a biarch 64-bit system starting with the 64-bit
compiler, by adding -m32 to the configure variables CC, CXX, etc... except
that this miserably breaks for GNATBIND and GNATMAKE.
Fixed thusly, tested on i586-suse-linux, applied as obvious on mainline, 4.6
and 4.5 branches.
