Subject: revamp makefile, build and link objects instead of #include'ing them
X-Git-Tag: gsoc-final~88
X-Git-Url: https://uglyman.kremlin.cc/gitweb/gitweb.cgi?a=commitdiff_plain;h=d5200a78f738245171a945526688e05b673a68e4;p=systembsd.git

revamp makefile, build and link objects instead of #include'ing them

previously main.c #include'd files which themselves #include'd all source
files. now, we (correctly) build objects from the genfile, which are linked
to our sources.
