toolchain/gcc: Backport patch to fix unconditional MULTIARCH_DIRNAME

2019-12-22T23:31:20Z

This backports the patch for GCC PR target/89587 (gcc's rs6000 configuration unconditionally sets MULTIARCH_DIRNAME, even when multiarch is disabled). This currently affects apm821xx and may cause issues when cross-compiling packages, e.g. Python 3[1]. This includes patches for GCC 8 (with the changelog diff removed); this change is already included in GCC 9.2 and 7.5.

toolchain: fix gcc depends on kernel headers

2019-09-04T11:35:53Z

GCC needs the kernel headers to compile. Some GCC file includes asm/unistd.h which is provided by the kernel headers. Normally the kernel headers build is very fast and ready before the gcc uses it, but if it clones the kernel from a slow git repository it takes longer and then it could be that the gcc already wants to use the kernel headers before they are available. This patch fixes this problem by adding the missing dependency. Signed-off-by: Hauke Mehrtens (cherry picked from commit b20156ba704ed8e03d030b2f294d8d19bebd2f71)
