Greetings,

As it is generally a good idea to allow the user to override CFLAGS and
LDFLAGS (automake based systems manage this with AM_CFLAGS vs CFLAGS),
here's a patch that does so.  The key is to keep options that are
required to build, along with include and link paths relative to the
source dir seperate from those that should be overridable (warning
flags, debug flags, optimizations, include/lib paths outside the source
tree).  Rather than adding another couple variables, I made use of the
GNU make 'override' directive.
