Yes, that would be great (committing first, then changing)

Ah, yes, libtool, that was it.

I think so - having it in the entry Makefile means that whether a
package is cross-compilable or not can be determined a priori from the
dependency graph. That doesn't come from bulk build reports. It also
is liable to change dynamically, and having separate reports from a few
days back might not help in that case.

Yes, a huge OK from me to commit - all the patches - I would be very grateful!
