I ran into this problem using a non-dumped Emacs (CANNOT_DUMP=yes) on
x86-64. The problem is temacs either doesn't set exec-path or it sets it
to nil — I'm not sure which. There's a bug in call-process that prevents
it from working correctly even for absolute paths when exec-path is nil.
The bug comes from the for loop in openp(), which requires at least one
iteration to successfully resolve an absolute path (so *any* non-empty
exec-path list will do).
This combination of issues makes it appear that temacs can't run
subprocesses, but it really just needs some help.
