A non-distribution-specific way to do it is to set a CFLAGS environment
variable, something like:

export CFLAGS='-O3 -march=i686'

You might also want to "export CXXFLAGS=$CFLAGS" for C++ stuff to
compile with the same optimizations.  And, of course, you might want to
set those in your ~/.bash_profile or something.

Of course, replace my example with the actual gcc options you would want
to use.
