[Bug bootstrap/35628] New: gcc-4.3.0 fails to build, mpfr problem, libmpfr.dylib, file is not of required architecture

["bill at cse dot ucdavis dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

I built gmp-4.2.2:
./configure --prefix=/opt/pkg/gmp-4.2.2
make
make install

And mpfr-2.3.1:
./configure --prefix=/opt/pkg/mpfr-2.3.1 --with-gmp=/opt/pkg/gmp-4.2.2/
--with-gmp-build=/opt/src/gmp-4.2.2/
make
make install

Oh the compiler I'm trying to install 4.3.0 (as well as gmp and mpfr) with:
Target: powerpc-apple-darwin9
gcc version 4.0.1 (Apple Inc. build 5465)

Then gcc:
./configure --prefix=/opt/pkg/gcc-4.3.0 --with-gmp=/opt/pkg/gmp-4.2.2
--with-mpfr=/opt/pkg/mpfr-2.3.1

And get:
checking for correct version of gmp.h... yes
checking for correct version of mpfr.h... no
configure: error: Building GCC requires GMP 4.1+ and MPFR 2.3.0+.

gcc-4.3.0 root# ls -al /opt/pkg/mpfr-2.3.1/include/mpfr.h 
-rw-r--r--  1 root  admin  37381 Mar 18 11:53
/opt/pkg/mpfr-2.3.1/include/mpfr.h

config.log has additional info:
configure:4573: gcc -o conftest -g -O2 -I/opt/pkg/gmp-4.2.2/include
-I/opt/pkg/mpfr-2.3.1/include   conftest.c  -L/opt/pkg/gmp-

ld: warning in /opt/pkg/gmp-4.2.2/lib/libgmp.dylib, file is not of required

I searched the bug database and found some mention of an unintentional --target
being supplied to gmp/mpfr, presumably it's the wrong --target.  I didn't
however find a fix, nor was I sure it was exactly the same problem.

The closest bug I found was #35250
