Saul Wold fe31dcd2a1 arch-x86: Add x86-x32 to MACHINEOVERRIDES
This is needed as an x32 more generic x32 override later in the
OVERRIDES, currently linux-gnux32 is the first override, but we
need a stronger (later in the list) x32 override to deal with some
needed x32 dependency overrides.

  • Initial version

Most of the items for the X86 architectures are defined in the single arch-x86 file.

Three ABIs are define, m32, mx32 and m64.

The following is the list of X86 specific variables:

X86ARCH32 - This is the 32-bit architecture GNU canonical arch, TUNE_ARCH.

X86ARCH64 - This is the 64-bit architecture GNU canonical arch, TUNE_ARCH.

The TUNE_PKGARCH is defined as follows:

TUNE_PKGARCH = ${TUNE_PKGARCH_tune-${DEFAULTTUNE}}

The package architecture for 32-bit targets is historical and generally set to to match the core compatible processor type, i.e. i386.

For 64-bit architectures, the architecture is expected to end in '_64'.

If the x32 ABI is used, then the _64 is further extended with a '_x32'.
