[PATCH]: fix the --with-mpfr-dir=PATH configure flag

[Philippe Schaffnit]

Hi!

I'm not adding anything new to this thread, but I gathered you wanted to
gather some feedback on it...

I'm extensively using the "--with-mpfr=" "--with-gmp=" (I often build
gfortran on machines on which I do not have administrator's privileges),
so I do see some use for these ones, I cannot comment on the '*-lib'
though (as already pointed, 'make install' seems a small price to
pay...).

Cheers!

Philippe
