Improve POSIX Make compatibility

[lanodan]

What remains non-POSIX is ifeq which pdpmake has but NetBSD make doesn't.

and the point is ? one needs gnu make anyway, and it's small and nice:

~ $ du -hs /opt/make/bin/make 
188.0K  /opt/make/bin/make
~ $ file /opt/make/bin/make 
/opt/make/bin/make: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, stripped

that's gnu make 3.82, ftr.

Mainly bootstrapping from full source, GNU make requires: - running the ./configure blob generated by autotools (which pulls perl if you want to regenerate it) - requires most shell utilities (sed/tr/mkdir/…) to be already present - (optional but would create an extra build stage) gettext Meanwhile pdpmake explicitly supports being compiled like so: $CC $CFLAGS -o /bin/pdpmake *.c
