[oe] Should be xserver-xorg MACHINE_ARCH?

[Martin Jansa]

Today I was checking why building om-gta01 and om-gta02 in same tmpdir
fails with this error:

 * satisfy_dependencies_for: Cannot satisfy the following dependencies for task-shr-minimal-x:
 *      libdrm (>= 2.4.18+gitr4565+b5aec2bd3df736216e86eae28e278172d3ba3362) *  libdrm (>= 2.4.18+gitr4565+b5aec2bd3df736216e86eae28e278172d3ba3362) *  libdrm (>= 2.4.18+gitr4565+b5aec2bd3df736216e86eae28e278172d3ba3362) *

first I noticed that task-shr-minimal.bb was missing
PACKAGE_ARCH = "${MACHINE_ARCH}"
after I moved some machine specific depends there (from shr-image.inc).

But even after that setting PACKAGE_ARCH right, I have this error and I think 
it's because xserver-xorg was built first for om-gta02 with virtual/libgl 
provider set to mesa-dri (_git.bb version used) and resulting .ipk has armv4t
arch, even when it was built with machine specific virtual/libgl provider and
libdrm version also specific for om-gta02 (om-gta01 will use 2.4.18 release instead,
because it doesn't need glamo specific patches from libdrm_git.bb)

What is right solution? Set xserver-xorg arch to MACHINE_ARCH (as virtual/libgl is
usually decided based on target machine). Or force om-gta01 to use mesa-dri (I already
did) and also libdrm from git repo with glamo patches (because upstream git repo and 
glamo repo has different SRCREV so switching to libdrm_git.bb won't help).

Thanks!

Regards,

BTW: I think we're going to have the same problems as when someone want's to build different
distributions in same tmpdir.

Looks like I should always use distro override instead machine override, because with machine
override I'm creating the same problem as above for other distributions building more machines
in same tmpdir.
