Well, upon in the beginning it was 3 pass. You need pass 1 to build gcc
without libc. Then you could build glibc headers. Then you build gcc
pass 2 with glibc headers so it targets right c-library, and you can
build full glibc. Finally you can build the final gcc as pass 3. Maybe
this was simplified too.

Seems there was bitrot in the cross building support. abuild was
improved, and upstream packaged changed.
I made same fixes to various places now. And will push all aports
changes today/tomorrow. After gcc 6.1 is done.
I'm playing with armv7 target, and got:
- full cross complier done (createcross-toolchain.sh runs)
- cross building boot image works up to building openssl; seems
something changed upstream and needs fixing
I hope to get the scripts / aports' minimal cross-building support to
the point that bootstrapping works again.
