on a PPC (OS/X at least) the default is the (slightly) slower PIC mode. For
programs there is the "-mdynamic-no-pic" which should be used for non-shared
(but still dynamic) objects such as compute bound programs. On IA32 there
is the "-fno-PIC" which simply restates the default of non-pic code.
Thus far only a couple programs in lavtools/ have had their CFLAGS adjusted
to show how it's done. Over time other cpu intense programs will have the
same mods made.
