No, I think shlibs-lds.patch was in there by mistake, it's ok that it
doesn't apply.  I've removed it for the next release, and have changed
getandpatch.sh to abort properly when patches don't apply (I hope).

I'll try to reproduce your problem on Linux, but be warned, we have never
bothered figuring out why crosstool.sh doesn't run properly on cygwin,
so you might run into more problems once this one is solved.

BTW you're not the only one seeing this error, and it's not (always) cygwin-specific; see e.g.
