This worked 2001-11-20:
../egcs/configure --target=sparc-x-elf
cd gcc
gmake tconfig.h
But now it has a dependency problem on `../libiberty/libiberty.a'.
Anyone know if this is new breakage, or if I was lucky before?

Intentional. We added support for a build-side libiberty, and the
gen* programs link with it. You must build the build-libiberty before
any of the gen* programs.
*Which* libiberty to build differs depending on the build; if
build==host, it's ../libiberty. If build!=host, it's
../$build/libiberty.

What is a "build-side" libiberty?

This is for the configury change checker script. Ie, it builds tconfig.h
from stock files and from a modified tree and diffs the two. Previously
I only configured the gcc/ as it was much faster than running configure
from the top-level directory. Note I usually do 20-35 targets at a time
(which means 40-70 runs of "configure+make tconfig.h").
What is the fastest way to configure+build tconfig.h with this change?

It's a libiberty built for the --build machine, to handle the cases
where build!=host.

You can configure+build libiberty separately, just like you are for
gcc.

What DJ told you is all correct, however, I'd appreciate your
repeating that with "gmake --debug" and sending me the output (no need
to spam the whole list with it). I don't believe it should be
necessary for tconfig.h to depend on gengenrtl; there may be a
dependency bug.
It may turn out to be legitimate - has been a long time since I was
digging in this area.
