I like this approach. I actually thought about making a build system
where the equivalent of would be a fragment which would be
included in a larger makefile, until I realised that the syntax I
would use would be similar to that already used in, so I
might as well base my work on automake. The automake syntax is mostly
make syntax which makes what you've done possible. I would definitely
have had a look at antimake had I known about it a couple of months

antimake and automake-ng (fork of automake targeting GNU make only)
require GNU make. The changes I've made also introduce a few potential
incompatibilities with make's other than GNU make, but I'm hopeful
that these will be minor and we can perhaps even generate Makefiles
for other makes as well. I think the idea of generation of portable
build systems using portable make and portable shell is sound, even
though it does make things more difficult.
