You probably also want the triple "armv7-unknown-linux-gnueabihf".
Straight away that would make your arm_aapcs_vfpcc annotations
redundant because that's the default.

Also, plain "gnu" is a really weird old ABI that LLVM doesn't actually
support so you could easily get strange behaviour from the backend not
dealing with it properly. And even if the backend gets it right
somehow, your surrounding libraries are almost certainly not "gnu".

Cheers.
