* Add support for marker type relocations. These mark areas
of interest to the linker. ENTRY/EXIT relocations for SOM are
an example of marker relocations.
* write.c (write_relocs): Instead of assuming size of a relocation
is 4 bytes, pick up the size from relocation itself.
(fixup_segment): Do not complain that a value is too small for
marker relocations.
