This requires further changes to linker script to KEEP some tables
and wildcard compiler generated sections into the right place. This
includes pp32 modifications from Christophe Leroy.
When compiling powernv_defconfig with this option, the resulting
kernel is almost 400kB smaller (and still boots):
text data bss dec filename
11827621 4810490 1341080 17979191 vmlinux
11752437 4598858 1338776 17690071 vmlinux.dcde
Mathieu's numbers for custom Mac Mini G4 config has almost 200kB
saving. It also had some increase in vmlinux size for as-yet
unknown reasons.
