alpha currently only supports static builds and no threads, IIRC.

This was already fixed, build tested fine for me some time ago.

Didn't try this in a long time.

This is fixed with gcc trunk (i.e. 4.4.0).

Would need love as it's a bit outdated.

s/broken/not yet supported/

both sh64 and sh* build fine for me.

never tried any sparc

works for me. What's failing?

there are SH and SH64. SH[234] are just SH variants -- think
i?86 or mips?e{l,b}

Strictly speaking this should depend on !BR2_TOOLCHAIN_BUILDROOT until
it is supported in uClibc. I agree that it could just me removed from BR for now.
