nixpkgs/pkgs/os-specific/linux/broadcom-sta/i686-build-failure.patch
aszlig bd7ce1581d
broadcom_sta: 6.30.223.248 -> 6.30.223.271
The patch for kernel version 3.18 is already applied upstream, so we
don't need it any longer.

Without i686-build-failure.patch, the build for i686-linux fails because
it references rdtscl(), which is no longer available in Linux 4.3.0.

Patch for missing rdtscl() is from Arch Linux:

https://aur.archlinux.org/cgit/aur.git/tree/002-rdtscl.patch?h=broadcom-wl-ck

I've tested building against 32 and 64 bit Linux versions 3.18.36,
4.4.16 and 4.7.0.

The hashes were verified using the ones from the AUR (using the 16 bit
hashes of course):
