Hi Blindcoder,

it's actually very simple: just install mpfr onto your build system. 
This is similar to e.g. requiring pre-installed bzip2 or patch tools, 
although earlier gcc versions did not need mpfr in stage 0 afaik.
Another possible option I think would be to built a native mpfr in stage 
0 before gcc, but this would (slightly) increase the complexity and 
overhead of each build, while pre-installing mpfr is usually not a problem.

With best regards,
Stefan Fiedler
