For x64 and x86_32 configurations, apply the -march flag to both GCC and
Clang flags.
This solves the problem of Clang-compiled coreboot failing due to Clang
emitting SSE instructions for code that is executed while SSE is not
enabled.
This patch takes functionality targeted for GCC configurations and moves
it down a few lines, modifying CFLAGS instead of GCC_CFLAGS in order
that it applies to both GCC and Clang.
This is an alternate patch to CB:32887.

The __pci_driver and __cpu_driver uses variable length arrays which are
constructed by the linker at build-time.
The linker always place the structs at 16-byte boundary, as per
"System V ABI". That's not a problem on x86, as the struct is exactly
16 Bytes in size. On other platforms, like x86_64 it breaks, because the
default data alignment isn't SysV compatible.
Set -malign-data=abi to make x86_64 gcc use the SysV psABI.

overwriting some of the array with other values:
u8 mainboard_picr_data[FCH_INT_TABLE_SIZE] = {

clang does not like that behavior unless we specify
the option -Wno-initializer-overrides.

clang, like gcc, needs a compiler runtime library. Unlike gcc, it can
use either its own runtime library (compiler-rt), or gcc's version
(libgcc). Also unlike gcc, the version of clang that is currently part
of our reference toolchain does not provide the necessary versions of
compiler-rt for all platforms we support. Hence, for now, use libgcc
even on clang builds. This patch allows switching between the two, but
switching to compiler-rt will break clang builds, unless someone fixes
our reference toolchain to provide libclang_rt.builtins-${ARCH}.a for
each of our supported platforms.
