Simplify CFLAGS/DEFINES in Makefile
I think the original intention was to make CFLAGS overridable from the make command line, but somehow we ended up accumulating conditional makefile sections that wrongly appends values to CFLAGs. These assignments do not work when the user actually override them from the make command line! DEFINES are handled the same way; it was seemingly overridable, but the makefile sections had assignments, which meant overriding it from the command line broke things. This simplifies things by limiting the internal futzing to ALL_CFLAGS, and by removing DEFINES altogether. Overriding CFLAGS from the command line should start working with this change.
