Bootstrap of GCC mainline on powerpc64-unknown-linux-gnu fails on some
distributions with an ICE while building libiberty in stage3, using the stage2
compiler:

Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
------------------------------------------------
The failures start with r145204, a merge from pretty-ipa, and go away when that
patch is reverted from current mainline. Since the failures happen on some
sysems (two different machines running SLES10) but not others (SLES9, RHEL4.3)
it's possible that they are actually intermittent and not really related to
this revision at all, or are due to a latent bug.
I tried starting from different versions of GCC and it made no difference. The
builds on all of these systems used binutils-2.19.
Configure options (other than prefix/with-gmp/with-mpfr/with-as/with-ld) were
--with-cpu=default32
--with-long-double-128
--enable-secureplt
--enable-languages=c
It also fails, in a shorter time, with
--build=powerpc-linux
--host=powerpc-linux
--target=powerpc-linux
--with-long-double-128
--enable-secureplt
--enable-languages=c

Surprise, Richard, you fixed this! The failure goes away with r145494, the
merge of the alias-improvements branch.
