Title: make mpfr and gmp compile-able under PPC

I update these two formula for ppc in order to build **gcc-4.6.2** under **iBook G4 10.5**.
Remove unnecessary checks that will add `-m32` to compiling options.

BTW, for those who wanna run **rtorrent** under PowerPC books,
I also updated _libtorrent_ and _rtorrent_ formulas, both of them requires newer G++'s STL.
(At least GNU GCC 4.2 instead of Apple GCC 4.2)

And a PPC compile-able gcc-4.6.2 as follows,
