uClibc build fails: missing libgcc_eh.a

uClibc build fails: missing libgcc_eh.a

[Grant Edwards]

I'm trying to build a pretty generic toolchain using ct-ng 1.12.0 for 
arm926, gcc 4.4.6, uclibc 0.9.32 linux-2.6.30, and it fails thusly:

From what I've been able to gather, libgcc_eh.a isn't being built, but
it's being linked in during the uClibc build.  What have I done wrong?

The same configuration with uClibc 0.9.30.3 appears to build OK.

Does uClibc 0.9.32 build for others?

Based on a thread I found in the uClibc mailing list, I think the
dependancy on libgcc_eh.a might be specific to arm-eabi...

And it fails with the uClibc version set to "snapshot".
