As a work-around, I defined CC='gcc-4.2 -m64 -mtune=970' and removed
CFLAGS.  (Similarly for CXX.)  I also added SHELL=/bin/bash because
/bin/sh is not bash.

With this, ppg and friends built correctly but now the build stops at
multilib:

Checking multilib configuration for libgm2...
mkdir powerpc-apple-darwin9.8.0/libgm2
Configuring in powerpc-apple-darwin9.8.0/libgm2
configure: creating cache ./config.cache
configure: error: cannot find install-sh, install.sh, or shtool in 
"../../../../src/gcc-4.7.3-patched/libgm2" 
"../../../../src/gcc-4.7.3-patched/libgm2/.." 
"../../../../src/gcc-4.7.3-patched/libgm2/../.."
make[1]: *** [configure-target-libgm2] Error 1

Indeed, none of those files are there but whey is it even looking?
This I do not understand because I specified --disable-multilib in my
configuration:

SHELL=/bin/bash \
CC='gcc-4.2 -m64 -mtune=970' \
CXX='g++-4.2 -m64 -mtune=970' \
LDFLAGS='-m64 -mtune=970' \
../../src/gcc-4.7.3-patched/configure \
--prefix=$HOME/gm2-4.7.3 --exec-prefix=$HOME/gm2-4.7.3 \
--with-mpc=/usr/local \
--with-mpfr=/usr/local \
--with-gmp=/usr/local \
--enable-languages=c,c++,gm2 \
--disable-multilib \
--disable-bootstrap --enable-checking --disable-libitm \
--enable-libgm2

Please advise on any thoughts on how to proceed from here.
