It's a bit more complicated

OE om-gta02 at shr ~/dev/recipes/xorg-xserver $ bitbake -e -b
xserver-xorg-conf_0.1.bb | grep ^OVERRIDES
OVERRIDES="thumb:thumb-interwork:libc-glibc:pn-xserver-xorg-conf:fail-fast:build-linux:arm:linux-gnueabi:shr::om-gta02:local:armv4t:armv4t"

that empty :: between shr and om-gta02 (where MACHINE_OVERRIDES should
be) is breaking it for both orders (ie ignoring all after om-gta02 or
after shr from with reversed order)

This is part of filespath (for first FILESPATHPKG - ${PF}) from
base_do_unpack in base.bbclass:
'/OE/dev/recipes/xorg-xserver/xserver-xorg-conf-0.1-r36/task-unpack'

        -- here is the problem
