MIPS/BFD: Report `bfd_reloc_outofrange' errors as such
A `bfd_reloc_outofrange' condition from `mips_elf_calculate_relocation'
currently triggers the warning callback, which in the case of LD prints
messages like:
foo.o: In function `foo':
(.text+0x0): warning: JALX to a non-word-aligned address
or:
foo.o: In function `foo':
(.text+0x0): warning: PC-relative load from unaligned address
and nothing else, which suggests this is a benign condition and link has
otherwise successfully run to completion. This is however not the case,
the link terminates right away with no further messages and no output
produced.
Use the general error or warning info callback then, preserving the
message format. Also set a BFD error condition so that a failure is
unambiguously reported. Complement the change with a set of suitable
test suite additions.

Call `bfd_set_error'.
