staging: Handle races between binaries and their libs
There is a long standing issue where a binary could be installed into the
sysroot before its library dependencies. We've always argued nothing should
use the binary until it has been installed by a dependency but there are issues
around binaries which conflict with the host system, for example patch,
python3, gzip and more.
With the recent patch changes we've seen issues like:
ERROR: gdb-cross-canadian-powerpc-8.3.1-r0 do_patch: Command Error: 'quilt --quiltrc /home/pokybuild/yocto-worker/qemuppc/build/build/tmp/work/x86_64-nativesdk-pokysdk-linux/gdb-cross-canadian-powerpc/8.3.1-r0/recipe-sysroot-native/etc/quiltrc push' exited with 0 Output:
Applying patch 0009-Change-order-of-CFLAGS.patch
patch: /lib64/libattr.so.1: version `ATTR_1.3' not found (required by patch)
Patch 0009-Change-order-of-CFLAGS.patch does not apply (enforce with -f)
which is a symptom of this issue (libattr-native is a dependency of patch-native).
There are other ways to fix this such as disabling libattr in patch, installing
patch to a subdirectory and requiring PATH manipulation and so on.
We can simply fix the staging code to handle /bin/ after everything else so
do that and avoid all these other complications.
