[Freeciv-Dev] (PR#3515) Adding -O3 -fomit-frame-poiter with --enable-debug=no

["Rafa³ Bursig" <bursig@xxxxxxxxx>]

Hi

  This code add -O3 -fomit-frame-pointer as default flags and turn off 
debuging with --enable-debug=no setting. Default setting is still 
--enable-debug=some which give -g -O2 flags.
