[RFC] -Os and -O2

[Vladimir 'phcoder' Serbinenko]

Hello. Current GRUB2 optimisation strategy is to compile whole grub
with -Os but only kernel, bus modules, disk modules, partmap and fs
modules have size concerns. Graphical modules have speed concerns. So
I propose following optimisation strategy:
-Os for kernel, bus modules, disk modules, partmap and fs
-O2 for other modules
