* PRYSM-2849 first cut at multi-arch cross compiling toolchain. currently supports arm64 and amd64 via docker cross compiler image * picky linter * some readme cleanup * remove arm 8.2 revision for arm64 builds (cortex a72 is ARMv8.0-A) remove arm32 toolchain from multiarch dockerfile * remove extranous WORKSPACE entries * add docker remote execution configs for amd64 and arm64 * add osx bazelrc configs * working osx toolchain * update readme * cleanup for amd, arm and osx cross before beginning windows * initial stab at mingw windows cross * add docker target for windows_amd64 and update readme for cross-compiling * little more cleanup for readability * Check in generated RBE. Still tweaking config but linux amd64 -> linux amd64 on RBE works OK. Cross compile does not work properly in RBE yet. * fix * update image * Making some progress * delete artifacts * Working build * Add remote config * remove some things I added to README * Tidy * Update readme * remove 2 commented lines * buildifer * Merge pull request #1 from prysmaticlabs/cross-compile-with-suburbandad Cross compile with suburbandad * Merge branch 'master' into clang-cross-compile * buildifier on generated stuff * Merge branch 'master' into clang-cross-compile * Merge branch 'master' into clang-cross-compile * Merge branch 'master' into clang-cross-compile
