My understanding of why NetBSD still uses binutils 2.16.1 is for
ideological reasons; later versions are all GPL3.  I can roll my own
binutils and use that to compile, but I thought it was worth noting to the
list that there are modern distros that can't compile x264 in its current
state.  OpenBSD appears to still be using binutils 2.15, which is even
worse; I'm not sure what FreeBSD is using.

Disabling assembly support entirely would be shooting myself in the foot,
so I'm not going to go that route.
