[OE-core] [DO-NOT-MERGE][RFC][PATCH] DO-NOT-MERGE: distutils3.bbclass: Don't use MACHINE variable

[Martin Jansa]

The original patch says this about MACHINE variables:

    Use MACHINE for sysroot when not building for build host

    Python's machinery replaces directories in sysroot path to match OE's
    staging area sysroots. Earlier we use to have HOST_SYS represent sysroot
    always but now we use MACHINE to represent target sysroots but HOST_SYS
    to represent host sysroot. This patch caters to that difference

But I think we need to find some different solution, because right now the only
user of distutils3 bbclass python3-distribute becames effectivelly MACHINE_ARCH
because of this. Detected with sstate-diff-machines.sh script:
