Agreed but I think that's necessary: In yocto builds we have two
separate sysroots native & cross. For each of them we have separated
build steps. As far as I know (I haven't seen that or managed to do
so) there is no chance to build native binaries from cross build step.
To access native tools during cross build they must be installed in
native sysroot.

I think this and Stephan's hints (at least saxparser.rdb is not
accessible during my cross build - and I was not aware of
URE_MORE_SERVICES environment var - so my gdb sessions missed that)
are good hooks to continue.

Will give those a try tonight - implementing liberoffice in yocto is
just a hobby for fun..
