provide a workaround for a glibc and GNU make incompatibility

Versions of GNU make newer than 4.4 trigger a hang in versions of glibc
older than 2.31. As distros update to the newer GNU make version we'll
start seeing more and more reports of this hang. Fortunately we already
carry GNU make as a comp tool so all we need to do is select the right
version when needed.

Fixes #1946, #1932, #1975
