Thanks a lot for testing it.

I found the explanation in the make info page:
`warning: jobserver unavailable: using -j1. Add `+' to parent make rule.'
In order for `make' processes to communicate, the parent will pass
information to the child. Since this could result in problems if
the child process isn't actually a `make', the parent will only do
this if it thinks the child is a `make'. The parent uses the
normal algorithms to determine this (*note How the `MAKE' Variable
Works: MAKE Variable.). If the makefile is constructed such that
the parent doesn't know the child is a `make' process, then the
child will receive only part of the information necessary. [...]
Which is our case: The parent make only sees the rpmbuild call. The fix
would probably be to clear all make environment variables before running
rpmbuild.

Another symptom of the same problem.

Great :).
