WIP. For now, while trying to reproduce this issue, I hit another one:

Tested this with the following local.conf:

....
#testcase for YB4358
require conf/multilib.conf
MULTILIBS = "multilib:lib32"
DEFAULTTUNE_virtclass-multilib-lib32 = "x86"
MULTILIB_IMAGE_INSTALL = "lib32-alsa-tools"

core-image-sato target for qemux86-64 machine build correctly (started from a "fresh" build dir).

Is this reproducible only on autobuilder?
If so, what is the test case?

Regards,
Cristian

The issue here is that aclocal is being called directly, not called by our wrapper in autotools.bbclass. We go to significant lengths to ensure the aclocal directory is "atomic" and that files in there can't change whilst aclocal is running.

The issue is that guile was installed in the sysroot and was uninstalled whilst the build was running. alsa-tools is running configure without the wrapper protection code.

the second problem you found is likely from changing the multilib configuration on an existing build directory. That problem is known about and is more a case of "don't do that!", its a problem in autotools not noticing changes in libdir and there is little we can do about it.

Fixed with commits:
