Did you check runtime for crashes? USE_GCC enforces libstdc++ which
conflicts with dependencies (e.g., qt5-*) built against libc++.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=221288#c4

USES=compiler:gcc-c++11-lib is a more safe way to use GCC to build a port on
architectures that switched to libc++ by default: aarch64, amd64, arm*, i386.
