Makefile: make portable, support static linking
We can happily stick to POSIX and the usual variable names,
with the following exceptions:
- pkg-config(1) is used to find libraries and compile flags
- the new "static" target uses non-standard compiler
and linker flags, though it's not the default target
sdn is predestined for wild distribution,
even the dynamically linked libc is rather suboptimal.
