In `make` 4.4, `fifo` is added and has been default value of `jobserver-style` option,
and error EAGAIN will randomly happen if `pselect` is disabled. In Termux, `pselect` in
make is disabled to solve issue #2983.

Error msg is like `make: *** read jobs pipe: Try again.  Stop.`. It is originally happened
on `termux-docker`, but can be reproduced on AVD (API 24, armv7a).

This issue is fixed upstream when porting z/OS.
