FS#5707 - Compiler optimisations for libmad on iPod 3G

I have found that there is a large benefit on the iPod 3g if libmad is compiled using -O instead of -O2.
This patch adds an extra environment variable, EXTRAMADOPTS, to tools/configure, and adds it after the normal libmad compiler options to allow different settings on a per-port basis.

It may be worth testing the effects of changing this option in other ports.

This also gave a speedup on 4g and later ipods, so I amended your patch accordingly before committing. Thanks!

Following discussion with linuxstb here is an updated version of the patch.
It does not add the environment variable, and instead uses a conditional in the libmad Makefile.
