Re: proposal: change default X11_TYPE on netbsd-6 to modular

pkgsrc Xorg doesn't build on -6-0. libLLVM is dying on an undefined
reference. It's building with pkgsrc gcc and possibly not linking
against pkgsrc gcc libraries.

http://nyftp.netbsd.org/pub/pkgsrc/packages/reports/2017Q1/NetBSD-6.0-x86_64/20170330.0531/libLLVM-4.0.0nb1/build.log

It can likely be worked around with not requiring llvm on netbsd-6, but
that's not a netbsd-6 specific bug.
