Not sure whether this is a valid bug against app-shells/quoter, sys-devel/crossdev, neither or both. I have a similar bug against sys-devel/gcc https://bugs.gentoo.org/show_bug.cgi?id=653898. But in this case setting CC, CXX and CPP doesn't fix it. I opened this bug because the ebuild is a simple Makefile. So it's easy to see that this ebuild does not support cross compiling other than by setting CC. And since sys-devel/crossdev doesn't set it, it makes me wonder how I know which packages do or do not support cross compiling other than by trying it.
