Subject: [PATCH] makefile changes

specify .POSIX: (already POSIX compliant, let's enforce POSIX behavior)
clear suffix list and only include .c as it's all we need
specify suffix rule .c to build binary and skip .o as it's not needed
remove LD as we're not using it anymore
remove OBJ as we're not building objects anymore
remove unnecessary input redirection for sed
in clean, remove all sinit tarballs not just for current VERSION
