[Bug bootstrap/43819] New: Bootstrapping GCC 4.5.0 fails with "cannot compute suffix of object files: cannot compile"

["florin at iucha dot net" <gcc-bugzilla at gcc dot gnu dot org>]

I'm trying to build GCC 4.5.0 on RedHat 7.3, using the included gcc compiler
version "2.96".  I have built and installed the dependencies (mpc-0.8.1,
mpfr-2.4.2, gmp-5.0.1) into /usr/local.296 and I tried to bootstrap gcc with
the following command line:

/tmp/gcc-4.5.0/configure --prefix=/usr/local.296/ --enable-shared
--with-system-zlib --enable-languages=c,c++ --with-gmp=/usr/local.296/
--with-mpfr=/usr/local.296/ --with-mpc=/usr/local.296/ --program-suffix=-450

I have also installed make-3.81 as RedHat 7.3 comes with 3.79 which is deemed
insufficient.

'make' cranks for a while and then it fails with:
