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

Finding mpfr in an installation directory via --with-mpfr=PATH
obviously works okay, or we'd all be hosed and would have noticed. :-)

It does not work if mpfr is in PATH/lib64. Am I the only one on x86_64 who
installed a 64-bit MPFR, or is RHEL odd in how it organizes its libraries?

So we need to search .libs, _libs and "." for libmpfr.a. The patch below
does this. The analogous --with-gmp-dir=PATH already checks these places
because I suspect gmp started using libtool earlier.

It would be really great if --with-mpfr and --with-gmp could also be made to
check lib64. If not for 4.1, then perhaps for 4.2 and trunk. By the way, I seem to
recall that 64-bit Ubuntu (?) uses lib32 and lib; this seems to necessitate checking
lib32 as well.

Would it be problematic if the libraries were installed in both lib and lib64, as 32
and 64 bits, respectively? I suppose if this is the case both paths should be used
-- the linker is smart enough to pick the correct one (gnu ld is anyhow).

Thank you for your help!
