It was up-to-date, but somehow mangled (haven't yet investigated
how/why). Anyway, with a fresh anon-CVS checkout of the 2.22 branch, I
can now build libgcc up to the failure point.

I wasn't completely certain about it and wanted to avoid a possible
source of problems.
I've now managed to reproduce the problem. In a checkout of the gcc
tree before my patches, unwind-dw2.o isn't built. I could trace this to
LIB2ADD_EH not being overridden any longer, so the default was used. I
had missed the addition of libgcc/config/c6x/t-c6x-elf since I've
normalized the names of the target fragments to consistently use
$cpu/t-elf, not $cpu/t-$cpu-elf.
Simply merging the contents of c6x/t-c6x-elf into c6x/t-elf allowed the
libgcc build to complete for me.
Here's the patch I've come up with. Should I commit it now or would you
like to do a full testsuite run first?
Sorry again for the trouble.
