Hi,
Attached is a patch to catch more sections.
Specifically, we need to catch
.text.*
.rodata.*
.data.*
.bss.*
to cope with newer versions of gcc emitting symbols in sections of the
form .text.foo.
Also, we need to include .ctor.* and .dtor.* to catch ctor symbols
with priorities. At the same time, we need to wrap those
ctor/dtor-related sections with KEEP so that the garbage collector
won't remove them.
Tested on fido-none-elf. OK to apply?

* libgloss/m68k/fido.sc: Catch .text.*, .rodata.*, .data.*,
.bss.*, .ctor.*, and .dtor.*. Wrap ctor/dtor-related sections
with KEEP.
