[Bug bootstrap/39001] New: lto branch doesn't build

[rguenth at gcc dot gnu dot org]

It doesn't build on SLES10 either, libelf0-0.8.10-36, it ICEs during
build of libgcc:

...

compiler error: Segmentation fault
Please submit a full bug report,

See <http://gcc.gnu.org/bugs.html> for instructions.

libelf shouldn't come into play while building, no?

this is on x86_64, the above ICE is with -m32.

The recent patch only fixes the case for x86_64.  This is still broken on ppc.
