[Halld-offline] DEBUG, PROFILE, OPTIMIZE

[David Lawrence]

Hi Mark,

     I not married to a particular default. We've just seen multiple 
instances lately where the DEBUG version seems to not display the 
problem so it seemed appropriate to create DEBUG, PROFILE, and OPTIMIZE 
variables to mirror the -g -pg and -O compilers options respectively so 
we have more control over them. If the general consensus is to include 
some kind of mixing matrix when converting the make options to gcc 
options, I'm fine with that. Let's discuss it at the next offline 
meeting (but perhaps limit discussion time to 10 minutes :) ).

Regards,
-Dave
