Libiberty issue vs cygwin [was Re: This is a Cygwin failure yeah?]

[DJ Delorie]

IIRC, that whole clause was because cygwin's dll itself linked with
libiberty, so the auto-detect stuff needed an override to make sure
the right files were there when you build cygwin1.dll.  Otherwise, it
would detect that cygwin had strsignal, not build it, then fail later
when cygwin1.dll couldn't find strsignal.

If cygwin no longer links with libiberty, that whole clause can
probably go away now.  As it's target-specific, I'm OK with letting
the target maintainers have the last word about it, too.
