This is documented here:
<http://www.gnu.org/software/autoconf/manual/html_node/C-Compiler.html#C-Compiler>
Quoting from it:

| If using the GNU C compiler, set shell variable GCC to `yes'. If output

| (-O2 on systems where GCC does not accept -g), or -g for other compilers.

That switch is not predefined by Autoconf or Automake.

Simply
  ./configure CFLAGS=-O2

(set CXXFLAGS etc. if you are using languages other than C as well).

Cheers,
Ralf
