If a command for a rule is a submake, but the command is contained in a
variable, then it can't run the submake in parallel. You get an error
message:
gmake[1]: warning: jobserver unavailable: using -j1. Add `+' to parent
make rule.
Here is a sample Makefile that shows the problem (for all versions with
the job server feature to 3.79):
#
ACOMMAND = $(MAKE) thing
default:
$(ACOMMAND)
thing:
@echo making thing
