I apologize as I have this in a topic on the forums, but most of my
recent questions of a similar vein have gone mostly unanswered there,
so I am posting to the ML as well:

gnat-gpl does not build after following
https://wiki.gentoo.org/wiki/Project:Ada. I did not set
FEATURES="nostrip" (enabling does not result in success) and set
ADA=x86_64-pc-linux-gnu-gcc-7.2.0. USE has "gnat_2017" set.

It seems like build fails when an internal set of GCC tools is built.

Cheers,
