gcc includes a nice library for getting c/c++ backtraces: libbacktrace.
This library should also be installed by the gcc ebuild.
Debian includes it in libgcc-4.8-dev and later (https://packages.debian.org/sid/amd64/libgcc-4.9-dev/filelist).
The files missing are mainly:
Please adjust the build to also install these files so that programs can use libbacktrace.
gcc specifically does not install it:
noinst_LTLIBRARIES = libbacktrace.la
you could file a request with them to have it be installed (at gcc.gnu.org), but i don't think we want to start exporting what looks like a purely internal library when upstream doesn't intend for it to be used externally.
Hmm, but why/how does debian do it then?
Anyway, I created a gcc issue: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66570

a scan of their deb rules looks like they do it all by hand which is what i want to avoid. that they choose to do so is up to their maintainers.
This is negatively effecting me.
Most other distributions provide libbacktrace, but Gentoo doesn't, and there's no practical way for an end user to address that.
Can't this be a USE flag?

I suggest prodding upstream bug report: https://gcc.gnu.org/PR66570
