[Gm2] gm2-4.7.3 on Mac 10.5.8/PPC: libgm2/configure deemed harmful

The story continues...

Last entry, libgm2/configure could not find non-existant files
and halted.  I created one of those non-existant files (a one-line
script to log arguments).  It was never called; the same jolly
libgm2/configure halted trying to run another non-existant file,
namely libgm2/config.sub.

Checking multilib configuration for libgm2...
Configuring in powerpc-apple-darwin9.8.0/libgm2
configure: loading cache ./config.cache
configure: error: cannot run /bin/sh 
../../../../src/gcc-4.7.3-patched/libgm2/config.sub
make[1]: *** [configure-target-libgm2] Error 1
make: *** [all] Error 2

Besides the non-existant config.sub, libgm2/configure is also invoking
/bin/sh, which is not /bin/bash. despite specifying SHELL=/bin/bash in
the configure script.
