I'm seeing the same problem in debian sid. Using debian stretch works fine.

[osresearch]

This should be fixed by the parallel build fix (in that we use the system make if the make is new enough)

[osresearch]

I'm re-opening this since it seems to still be a problem on ubuntu 18.04

[osresearch]

This defines __alloca so that it works on ubuntu 18.04: https://github.com/osresearch/heads/blob/make-4.2.1/patches/make-4.2.1.patch
