Building in the source tree is something the gnu tool developers
rarely, if ever, do.  Thus one guess for this particular problem is bitrot.
[insert notion that it's useful to have automated checks to keep
things like this working]

I'm guessing you meant libc  ^^^^^ here.
I don't know why this happened (and I don't recall a message from
Jeff, maybe he responded in private).

Evidently the sys_dir to configure comes from
I don't see it defaulting to linux for unknown x86 targets.
Did you add an entry to for i*86-pc-com32?
