[Bug c/40650] New: gcc-4.5-20090702 won't build on OS X 10.5

["hal at oz dot net" <gcc-bugzilla at gcc dot gnu dot org>]

The full 20090702 gcc 4.5 snapshot runs into a problem early in stage 2 on OS
X.  The last few lines of the console output are:

checking if the linker (/usr/libexec/gcc/i686-apple-darwin9/4.0.1/ld) is GNU
ld... no
checking for /usr/libexec/gcc/i686-apple-darwin9/4.0.1/ld option to reload

Configuration:  OS X 10.5.7 running on a macbook pro; xcode tools 3.1.3;
gcc-4.5-20090702 full snapshot with gmp-4.3.1 unpacked into the top-level of
the tree as gmp and mpfr-2.4.1 as mpfr.  Configured with default options; no
options specified for the configure script.

The full gcc-4.5-20090618 snapshot builds without trouble on the same machine
using that setup, including the same versions of gmp and mpfr.
