www/firefox uses clang++ as C++ compiler.
I think that GCC_REQD is not relevant to www/firefox.

Some parts in www/firefox require gnu++17, and some parts
require gnu++14 and they dislike gnu++17.
www/firefox cannot accept consistent -std=... flags.
Adding -std=gnu++14 or -std=gnu++17 to all c++ invocations
causes build failures.

If anyone has proper way to handle this situation of www/firefox,
feel free to fix this problem.

And I will find a time to fix the build on NetBSD/{i386,amd64} 8.

Thank you.
