libatomic constructs gcc_objdir using `pwd` and assumes
MULTIBUILDTOP is relative. Passing an absolute MULTIBUILDTOP
from OE results in malformed paths during libtool install
operations in both compile and install stages.
Avoid passing MULTIBUILDTOP for libatomic and use the upstream
default handling instead.

It would be good to start a discussion/bug in gcc about it, I think
using pwd relative paths is perhaps
less than ideal to use here. We can accept this additional logic here
for OE in the meantime.
Hi Khem,
I’ve filed a GCC bug for this issue here:
