I generally don't have problems with make in FreeBSD environments, but
often have tons of problems in others, like OpenSolaris,
buildroot/busybox, and so on. To solve this, I clean my environment by
using this shell script (called cleanenv):
#!/bin/sh
env -i PATH=/usr/bin:/bin TERM=${TERM} P4CONFIG=P4ENV $*
exit $?
or variants on this to run make (as in 'cleanenv make'). This tends to
try and limit the chaos from environment assumptions.
I don't think it is make's job, or the build tree's job, to enforce this
cleanliness- mostly because it's really hard to do. It's just a lot
easier to be a canonical simple 'user' when building.
