I didn't see it, but I might not have been in copy.
I just tried that:
[philipp@builder ~/openwrt2]$ cat /tmp/Makefile
$(info MAKEFLAGS=$(MAKEFLAGS))
$(info MFLAGS=$(MFLAGS))
$(info MAKE=$(MAKE))
PBUILD:=$(if $(filter --jobs% -j%,$(MAKEFLAGS)),y,)
all:
@echo PBUILD=$(PBUILD)
@$(MAKE) -f /tmp/Makefile stop
stop:
[philipp@builder ~/openwrt2]$ make -j5 -f /tmp/Makefile
MAKEFLAGS=
MFLAGS=
MAKE=make
PBUILD=
MAKEFLAGS=w
MFLAGS=-w
MAKE=make
make[1]: Entering directory `/home/philipp/openwrt2'
make[1]: Nothing to be done for `stop'.
make[1]: Leaving directory `/home/philipp/openwrt2'
[philipp@builder ~/openwrt2]$
Not sure what I'm missing...
