Reuse of reloc_howto_type depending on section

Hi Martin,

This makes sense.

Have a look at how it is done for other targets.  For example in 
bfd/elf-m10300.c:mn10300_elf_relocate_section (which calls 
mn10300_elf_final_link_relocate) there is code to compute the value for 
a variable called 'sec' which is the section containing the symbol that 
is referred to by the reloc.  You can then test the flags field of this 
structure to determine if the section is a code section.

Cheers
