[PATCH] SunCC default options

I recently noticed if you want to compile PHP using the suncc compiler, there are no useful default flags set by configure. Therefore if there are no objections I want to commit the following patch that introduces usefull cflags (actually those used by php distributed by sun) for the suncc compiler if the user didn't provide his own cflags. In addition it makes sure that --enable-debug works for suncc. I tested the patch with sunstudio 11 and sunstudio 12 c compilers. The patch is for 5.3 so I won't commit this to 5.2.
