While doing this I've encountered the following problem. Consider this
source file:

                .text
                .long   INITFN
INITFN:         nop



If I compile it with the old assembler, I get the following relocation
entry in the object file:


/tmp/yyy.o:     file format coff-z8k

RELOCATION RECORDS FOR [.text]:
OFFSET   TYPE              VALUE
00000000 r_imm32           INITFN


If I compile it with my BFD_ASSEMBLER modified version, I get


/tmp/zzz.o:     file format coff-z8k

RELOCATION RECORDS FOR [.text]:
OFFSET   TYPE              VALUE
00000000 r_imm32           .text


Please note the different VALUEs.

If I compile the same source file with i386-coff-as, I get the same
result:


/tmp/333.o:     file format coff-i386

RELOCATION RECORDS FOR [.text]:
OFFSET   TYPE              VALUE
00000000 dir32             .text


Shouldn't the VALUE be INITFN, like in the old non-bfd assembler?
