  This sounds like a REL-vs-RELA issue to me.  Perhaps the old assembler
produces a reloc with a value of 4, and places a zero in the .long at offset
0 in the .text section, while the new one produces a reloc with a value of
zero, and places the value 4 in the .long at offset 0 in the .text section?
You may need to switch the linker over if this is the case, or perhaps there
is an assumption in BFD_ASSEMBLER that the linker uses one format rather
than the other that isn't justified in this case?
