I don't know, not that I've heard of at least, but perhaps someone else
knows of something?

Yes, I believe so. If compiling with USE_PRIVATE_LIBGCC=no, the linker
can't find libgcc.

No.

Sorry. As Prafulla said, it's openrd_base. I sent patches from this
some time back,

  http://lists.denx.de/pipermail/u-boot/2009-July/055374.html

I'll send an updated version of the patch, but it can't go in until
mach-types.h has been updated at least. It's very similar to sheevaplug
though, but uses 64-bit vsnprintf since it needs UBIFS support. I guess
the nand_bbt problem is a similar issue.
