_______________________________________________________
Details:
If make < 4.2 calls a sub-make >= 4.2, jobserver information is not passed due
to the parameter having been renamed from --jobserver-fds to --jobserver-auth.
If the top-level make is parallelizing (i.e. in jobserver mode), the sub-make
inherits the "-j" in MAKEFLAGS but receives no jobserver pipe, thereby the
sub-make parallelizes jobs without an upper limit which leads to rapid
resource exhaustion when doing builds of big software packages (e.g. gcc).
The patch attached has been tested to successfully solve the problem in GNU
make >= 4.2. It simply handles the old --jobserver-fds parameter in addition
to the new --jobserver-auth one.
