The recommended way is to set the flags at configure commandline. Could 
you please try if the following also works:

./configure --prefix=/opt/gsl/gsl-1.14-Leopard --disable-shared CC=gcc 
CFLAGS='-isysroot /Developer/SDKs/MacOSX10.5.sdk -mmacosx-version-min=10.5 
-arch i386 -arch ppc' LDFLAGS='-arch i386 -arch ppc'

The INSTALL file comes from autoconf, so if any changes are needed we 
should probably report it upstream. IIUC, there is some code in automake 
to detect multi arch builds in order to turn off dependency tracking 
automagically. I'm not sure, however, whether you need to give *FLAGS at 
configure commandline or if the detection is supposed to work also when 
taken from the environment. Therefore, it would be useful to know if the 
configure call I described above works for you, or not.

Thanks,
Peter
