Re-run binutils-config manually, as this will fix the ldscripts bug, and then
source /etc/profile. Binutils-config doesn't do this automatically, so it's
caught a few people off guard.
Second, whenever you use an older config on a newer kernel, _always_ check the
config to make sure it didn't flip something off. Things changed dramatically
from .17 to .20, and relying on oldconfig alone isn't recommended. I usually
run through menuconfig and just check the categories myself.
That all said, nested exceptions sometimes point at ARCS bugs. You may have an
out-of-date PROM. Unfortunately, we're not sure which PROMs are out-of-date,
and which ones aren't.
