It's the usual BFD crock.  elf32-target.h is included twice--once by
elf32-arm.h, and once, for the Symbian stuff, by elfarm-nabi.c itself.

(I haven't tried to verify that Mark has done everything correctly,
but certainly the right framework is there).

(It would not be unreasonable to create a new file elfarm-symbian.c,
and make the appropriate functions and data structures in
elfarm-nabi.c non-static.)
