Cross compiling for evbarm on amd64

[Mayuresh <mayuresh%acm.org@localhost>]

This is nicely documented here:
https://ftp.netbsd.org/pub/pkgsrc/current/pkgsrc/doc/HOWTO-use-crosscompile

It's a great feature of pkgsrc if it can build packages for smaller
devices using larger computers.

I am trying to build for evbarm on NetBSD8, using cross compiled tools and
distribution of -current.

When building cross/cross-libtool-base I get the following error:

=> Bootstrap dependency digest>=20010302: found digest-20190127
ERROR: This package is not available for these platforms: Darwin-*-*
Interix-*-* *-*-x86_64 DragonFly-*-* NetBSD-[6789]*-*.
ERROR: This package has set PKG_SKIP_REASON:
ERROR: gcc2-2.95.3nb7 is not available for NetBSD-8.0-evbarm
*** Error code 1

What could be the way forward.
