Log message:
gcc 4.9 makes unknown -Wno-* vanish.
Reimplement that from scratch in our ancient gcc, because it's really
useful for porting newer code and dealing with compiler variations.
(slightly tweaked to reset location to unknown location after the okays)

found out https://gcc.gnu.org/bugzilla/show_bug.cgi?id=28322
after the patch, which explains a similar reasoning better, and leads
to another patch for older GCC, possibly GPLv3.
