fix breakage when user overrides CFLAGS on the make command line
these per-target CFLAGS adjustments are mandatory additions to the command line for building the affected targets, not part of the user-provided CFLAGS for tuning. my intent was always that the variable append operations would take place after user settings, but when a variable is set on the command line, it overrides all definitions in the makefile, including target-specific ones. based on patch by Szabolcs Nagy.
