Why would you want to explicitly add a lib, which you don't seem to have on your system? Either build gcc without mpfr (if that's possible at all) or build and install mpfr first (or use the dist's package) - That should usually fix your problem.

Thanks Ian,

I did that in the meanwhile, and I also attached this log to this
email. There seems to be a problem with mpfr, so I explicitly added it
during the configuration step, but that didn't change anything.

Have a look at it, ideas welcome.

And many thanks in advance,

Take a look at x86_64-unknown-linux-gnu/libgcc/config.log to see what
went wrong.
