This patch allows section overlap to be checked on a relocatable link.  Usually
this is a silly thing to do, because all output sections are placed at 0.
However, for vxworks images it can be useful, as a non-default linker script may
be being used to place sections sequentially.

The patch changes the check_section_addresses flag to be trivalued, so we can
distinguish 'default' from explicitly off and explicitly on.  When defaulted we
disable checking on relocatable linking (but it remains enabled on
non-relocatable links).  Thus preserving the existing default behaviour.

tested in powerpc-elf.  ok?
