Um, my toolchain is using the last gplv2 snapshot of binutils out of  
git, which is just past 2.17 and can build armv7 (but not armv8).

Binutils 2.12->2.22 is quite the jump. (11 years.) I'd except some  
thought to have gone into that? Possibly a mention of it?

When the sh4 platform did this, I just reverted the patch. (It still  
reverts cleanly ~4 years later, and builds with my old tool versions...)
