You're doing it the hard way.

For each gcc release for which there exists a
"contrib/download_prerequisites" script (may not apply to the very
oldest on this list)

use that script, to download a known compatible version of all required
libraries into a known compatible location.

Then (from your build directory)Â 
../wherever_my_sources_are/configure my_options
will find and configure to build the lot.

It won't use the latest and greatest version of mpfr etc for each
compiler release, but it'll use the version that most builds of that
release were built with, and keep you out of the weeds covering rarely
trodden paths.
