I don't remember.

The problem was related to libtool. And unfortunately "fix problem" and
"libtool" in the same sentence is fairly hard to have :-)

Honestly, I've spent quite a bit of time at this moment trying to find
the solution for the --sysroot option that would work with most
packages, without requiring to do horrible things. As things are
working today, I'm not really willing to spend more time on this, but
if others want, I of course won't prevent them from doing so. I'll just
ask for some heavy testing to be done before accepting changes on
this :-)

Hum, why ? Do you want to use the toolchain file even to build the
CMake-based packages in Buildroot ? Or just provide it for users to
build external softwares outside of Buildroot ?

As it should be part of the SDK, it should probably be located in
$(HOST_DIR) somewhere. But I'm not really clear yet on what the
organization of the SDK should be. In the mean time, just assume you
can put it in $(O), moving it to some other place won't be hard.

Thanks!
