Hi Naman,

Now this failure is a bit strange, because I'm having a hard time
reproducing this out of the autobuilder. The behaviour of the libtool
command in do_install_ptest() is different when I build locally.

So first, how can you reproduce this locally:

git clone https://git.yoctoproject.org/poky-ci-archive -b autobuilder.yoctoproject.org/valkyrie/a-full-2415
. oe-init-build-env
bitbake libmd
# Above build log is for lib32-libmd, but libmd should show the same
# error.

Now, on my computer, the build succeeds, while it fails on the
autobuilder.

The difference lies in the libtool command output. On both the
autobuilder and my computer, the input file is a shell script wrapper
generated by libtool. But on the my computer the output is a binary,
while on the autobuilder the output is the same script as in input. As
the script contains a reference to the build directory, it triggers the
QA error.

I will try to go further and understand why the behaviour is different.

Thanks,
Mathieu
