Get make check to work with -j again

[brson]

Several people have mentioned recently that -j doesn't work when running tests.

I just built successfully make -j check
Mac OSX 10.8.2
4 Hyper Threaded Cores

Did you specify -j#?

[nickdesaulniers]

From the man pages:
If the -j option is given without an argument, make will not limit the number of jobs that can run simultaneously.

Not critical for 0.7. Nominating for milestone 5 (production-ready).

[graydon]

declined; we will live if it doesn't do this

(bug triage) I run make -j8 check all the time, but if it doesn't work on some platforms, that should still be fixed.

Part of #8058

there are definitely problems relating to -j style options, but this particular bug might be too vague for us to work with. (I assume the core issue here is that -jK is not working for some K, not that the K-less variant -j is not working while the others are.)

For an example of such an issue, see #8057. (Though that is not one what I suspect to be going on here, unless people are only seeing this if they jump straight into make clean; make check instead of doing make clean; make; make check)

i'm closing this. We'll open new bugs as we discover them.
