genl Makefile LDFLAGS

genl Makefile LDFLAGS

The current genl Makefile sticks -lm and -ldl into LDFLAGS ... however, this
does not create the proper link order as the implicit Makefile rules will
place LDFLAGS before object files

attached patch uses LDLIBS for -lm and -ldl and make's implicit rule will
place them in the proper location

also, i removed the -s argument to `install` as install does stripping
improperly in many scenarios (such as cross-compiling) ... and in general,
it's nice if the decision to strip is handled by the sysadmin
