[edk2-devel] [PATCH] BaseTools/tools_def.txt: Add -march=x86-64 for X64 CLANG and GCC targets

From: dann frazier <dann.frazier at canonical.com>
Some Linux distributions are experimenting with builds that target a
higher x86-64 psABI, such as x86-64-v3. To avoid inheriting these
compiler defaults in edk2 builds, and therefore breaking compatibility
with machines using older CPUs, explicitly target the generic x86-64
psABI. This is similar to how we explicitly specify the cpu type for
some other architectures (-march=i586 for IA32, -march=armv7-a for ARM).
Spot tested with OVMF builds using GCC5 and CLANG38.
