BUILD_SYS is needed in python machinery to construct proper sys root
especially with python3 versions the cross build infra in python is
different. I think this patch would fail to build python3, either we
have to patch it in such a way that whatever sys root OE constructs is
passed directly and used and thereby remove depending on referring to
MACHINE but that would need a bigger patch for python which I was not
willing to carry. if there is another check that can deduce difference
of being compiled native or for target then we can use that check
instead of comparing BUILD_SYS to MACHINE
