[OE-core] Recipe which builds for ARCH '${TUNE_PKGARCH}' and 'all' fail

[Max Krummenacher]

Hi

If a recipe builds a package for the default ARCH (I think this is
${TUNE_PKGARCH}) and one for ARCH 'all' then this fails when building
in the same directory a second time for a machine with different
${TUNE_PKGARCH}.
Observed with dizzy (armv7at2hf-vfp vs armv7at2hf-vfp-neon) and
master (MACHINE=qemux86-64 vs qemuarm)


ERROR: The recipe mixed-arch-test is trying to install files into a
shared area when those files already exist. Those files and their
manifest location are:
   /mnt/sdc2/oe-disk/oe-core_master/oe-core/build/tmp-glibc/deploy/ipk/all/mixed-arch-test-a_1.0-r0_all.ipk
 Matched in manifest-core2-64-mixed-arch-test.package_write_ipk


An example in the wild is meta-java/recipes-core/rhino/rhino_1.7r4.bb
which builds: rhino_1.7r4-r0_armv7at2hf-vfp.ipk and
librhino-java_1.7r4-r0_all.ipk.

See below for a simple test recipe which reproduces the error.


Is this intended behavior or an issue oe-core?


Simple workaround:
- don't build machines with different architectures in the same build
directory.

Workarounds at recipe level:
- build all packages for TUNE_PKGARCH, even if the nature of the package
would be 'all'.
- have two recipes, one providing packages to TUNE_PKGARCH, the other
one to 'all'.
