Back-patch 9.4-era commit 384f933046dc9e9a2b416f5f7b3be30b93587c63 into the previous branches. Although that was only advertised as repairing a problem with missed header-file dependencies, it turns out to also be important for parallel make safety. The previous coding allowed two independent make jobs to get launched concurrently in contrib/spi. Normally this would be OK, because they are building independent targets; but if --enable-depend is in use, it's unsafe, because one make run might try to read a .deps file that the other one is in process of rewriting. This is evidently the cause of buildfarm member francolin's recent failure in the 9.2 branch. I believe this patch will result in only one subsidiary make run, making it safe(r).
