It sounds like you're the proper recipient of this error message then:

I was able to successfully build a toolchain using the buildroot scripts
on Friday, so this error is funny.  I have not yet verified that the
toolchain I built on Friday is valid: I got a "could not load init"
message.  Maybe I just didn't fully clean my tree before recompiling
with the SOFT_FLOAT tree: I'm going to keep trying.
