HOWTO references to bfd_elf_generic_reloc, that have

is based on the recent rewrite of m32r_elf_lo16_reloc(), and
extends its fixes to the R_M32R_{16,24,32} relocs.
The new logic in m32r_elf_lo16_reloc() has been removed, and
it instead calls the new routine to obtain that functionality.
complain_overflow_bitfield doesn't complain) from -2**(n-1)..2**n-1 to
-2**n..2**n. This might mean that some reloc overflows are no longer
caught, but it solves the address wrap problem for 16-bit relocs
nicely. In any case, ports that rely on complain_overflow_bitfield
for reloc overflow checking were not getting a very good check
previously. A bitfield range in a machine instruction is typically
either the signed or unsigned n bit numbers, not the overlap of these
two ranges.
