Not sure whether this is binutils-related or something else changed recently, but we are seeing some ports picking up libatomic.so from gcc-4.8 on i386.
As this is typically not listed in WANTLIB (only present in x11/ogre) build often fails, and of course there will be runtime problems for users who install the package but don't have gcc libs.

If the build is done with gcc present, it builds ok, and libatomic gets linked in to the produced object (so in this case the produced package is missing a required dependency on gcc libs). I discussed this with Antoine and we're not quite sure how to handle this in a non-horrible way. Do we need arch-dependent WANTLIB/LIB_DEPENDS on gcc libraries? (I also note that in gcc/4.9 this is in a libs package whereas in gcc/4.8 it's in the main gcc package). Or should we just enforce the dependency for all arch? Or does anyone have other ideas?
