If that doesn't work, feel free to borrow:

https://github.com/cygwinports/binutils/blob/master/2.24.51-shared-libs.patch

However, these libraries are (by design) API-unstable, so is not
recommended to allow other code to link against these shared libs,
therefore I would also suggest:

https://github.com/cygwinports/binutils/blob/master/binutils.cygport#L30-L38

Not sure, but if it's just so that 32-bit utils can read 64-bit
binaries (which is useful), --enable-targets=x86_64-pep should be
enough.

Yes, regardless.
