> I'm not sure why `unset MAKE` in `spkg-install` doesn't suppress
parallel intra-spkg builds/installs for Singular (#9185), R (#9186), or
ECL (#9187) on OS X. In particular, I don't know whether the source of
the problem is in `make`, OS X, or the Sage/spkg `Makefile`s. But setting
an empty `MAKEFLAGS` variable seems to work without causing problems on
other platforms.
IMHO, unsetting MAKE is a bad idea.
It is quite common for people to specify something like
{{{
MAKE=/usr/sfw/bin/gmake -j 10
export MAKE
}}}
with the vague hope of using 'gmake' rather than 'make'.
Rather than unsetting, one other possibility is
{{{
MAKE="$MAKE -j1"
}}}
if the aim is to stop more than one thread.
Of course, all this relies on people referring to variables and non hard-
coded names like 'make'.
I don't know if MAKEFLAGS is portable or not, but for now at least I guess
it will do.
