I saw cross compile disabled for g77 and objc. I enabled it by hand.
It seems to work for me from glibc 2 to libc 5 on x86. I also tried
from glibc 2/x86 to glibc 2/ppc.

?!? What are you talking about?
Did you actually read the instructions we provide for building cross compilers?
"make cross" is not the way to build cross compilers anymore. THe target
should be removed from the toplevel Makefile.

No. I used my old script.

Thanks. It works for me now. "make cross" did confuse me.
Here is a libgcc2 patch for cross compile. When I do cross compile for
Linux, I need a libgcc.a which is identical to the native compiled
libgcc.a. The current libgcc2.c doesn't support it. I used the patch
below to get around it. I added -Dno_inhibit_libc to my CFLAGS so that
my cross compiled libgcc.a is the same as the native compiled libgcc.a.
