I have now tried a world build on oe-core master/latest and I can
confirm that also I get build errors on a clean build root.
I only went as far as stopping at file-native. I think I need to debug
this problem package by package. Something is definitely spooky here.
On poky 1.4 it works like a charm, on current oe-core it does not. Also,
doing a clean sstate or building "file-native" separately
makes no difference. What I discovered is that the sysroot is
completely wrong. It has been resolved to "/" which means the wrong
set of libraries are picked up. If I patched the generated
x86_64-linux-libtool and replaced lt_sysroot with the actual sysroot in use
compilation went fine! The libtool patch *is* good. No question about
that. It is an obvious bug that has been corrected. To me this looks like
some kind of a double-fault! I need to dig deeper.
Thanks.
