Revert commit 9d96a7e0; it looks like it adversely affected the link
order of the many C$$data sections, causing the library chunks in the
ROM version of CLib to have incorrect size values for the static data
areas. (This also suggests that if GNUmakefile was used to build a ROM
version of CLib it could be broken in the same way)

Re-apply the relevant bits from 87239378 so that the new stub files are
still included.

Future commits will hopefully restore the safe bits of 9d96a7e0 (and
hopefully make things more robust)

Fixes issue reported on the forums with the ROM version of CLib
rejecting all ROM C modules (and probably all RAM C modules):
