[PATCH 2/3] local.conf.sample: Disable ARM and PPC due to prelink test case failures

[Mark Hatle]

Internal prelink test cases reloc8 and reloc9 are failing on both ARM
and PPC systems.  Disable them by removing the prelink from the
IMAGE_CLASSES setting.

Re: [PATCH 2/3] local.conf.sample: Disable ARM and PPC due to prelink test case failures

[Mark Hatle]

Just an FYI - I've investigated the ARM and PPC failures further.  It looks like
it may be a binutils problem.

Both of the failed tests link applications using the arguments "-Wl,-z,nocopyreloc"

Once this has been done, the executable will not run.  (Aborts very early.)

I'm currently verifying if this did work in the past.
