gcc command option used to build Debian

[Alexandre Bencz]

Hi
I would like to know which parameter is used in gcc, to compile debian, 
so that the relay works from G5 to IBM Power7...
Anyway, I would like to know this information, to compile a project that 
needs to work from G5 to Power7

is this option: *-mcpu=common *?*

Thanks
