archivers/unrar not MAKE_JOBS_SAFE ?

[Martin Husemann <martin%duskware.de@localhost>]

I have a strange problem: every time I try to build archivers/unrar
and MAKE_JOBS is set I get strange failures (missing .o files during
link, concrete files vary depending on phase of moon).

The makefile used is very simple and I don't see the problem.

Is it only me? Anyone spot the issue?

Martin
