gnu: cross-base: Apply Qualcomm's patches for Binutils and GCC.
This fixes compilation of the ath9k-htc firmware. Before that, loading it would result in "Target is unresponsive". The patches come from the ath9k-htc firmware source. * gnu/packages/patches/ath9k-htc-firmware-binutils.patch, gnu/packages/patches/ath9k-htc-firmware-gcc.patch: New files. * gnu-system.am (dist_patch_DATA): Add them. * gnu/packages/cross-base.scm (package-with-patch): New procedure. (cross-binutils): Check whether TARGET starts with "xtensa-", and call 'package-with-patch' when it does. (cross-gcc-patches): New procedure. (cross-gcc): Use it to add patches.

This GCC patch is from the ath9k-htc-firmware repository (version 1.3.2).
|
||||
Not applying it (apparently) leads to miscompiled firmware, and loading it
|
||||
fails with a "Target is unresponsive" message from the 'ath9k_htc' module.
