Cygwin x86 on Windows 10 ARM64

I've been trying out the x86 emulation in Microsoft's ARM64 version of
Windows 10 1803.

I had two issues with Cygwin x86. The first, which is simple, is that
Windows doesn't by default create C:\Windows\SysWOW64\drivers\etc which
causes /etc/postinstall/base-files-mketc.sh to exit with an error all the
time. I wonder if there's a possible workaround to make that less intrusive?
The error message implies that it may have computed the wrong directory,
which it hasn't - it's just that the directory doesn't exist.

The other is that all Cygwin binaries are emitting the "Could not compute
FAST_CWD pointer" warning.

Everything's up-to-date and I also tried it with the 2018-06-29 cygwin1.dll
snapshot.

Very happy to test things and poke around, I'd just need some pointers, if
you'll excuse the pun.
