There are at least two paths where it makes sense to run: /usr/local and
/usr. Whereas for the other cases I usually encounter building is done
as ordinary user and thus ldconfig can not run.
I guess (not sure though) cross-compilation already is a flag, so that could
be used for this, which IMO would be preferable.
Building packages is a bit different thing, but IMHO the solution would
be not to run as root ;-)
