pmaports/gcc-aarch64/011_all_default-warn-format-security.patch
Oliver Smith 925b78ae16 Official support for aarch64 (#84)
* Fix hardcoded `armhf` in pmb/aportgen/binutils.py
* Generate aports: `binutils-aarch64`, `musl-aarch64`, `gcc-aarch64`
* Distccd: Remember the cross-compiler architecture (currently armhf
  or aarch64), that the current distccd is running as, and restart
  distccd with the correct architecture, in case a different arch
  is needed than what it is currently running as. (Depending on the
  cross-compiler arch, the PATH variable gets adjusted before
  starting distccd)
* Testcases: add aport generation for aarch64, add cross-compiling
  to aarch64
* pmb/parse/arch.py: Add aarch64 to the mapping
