Can't the whole toolchain include ELF support as an alternative target?  Kinda
like "-m32" on x86_64.  I don't think it's unreasonable to request that Cygwin
provides this (and it'd probably solve other problems somewhere else).

Have you tried asking the Cygwin maintainers what they think about that?
