What we're trying to do here is allocate a toc section (early), and attach

written out before all files have been processed. This code allocates
a toc section for every file, and records the last one seen. There are
at least two problems with this approach:
1. We allocate whole bunches of toc sections that are ignored, but at
at least we will not allocate a toc if no .toc is present.
2. It's not clear to me that being the last bfd read necessarily means
that you are the last bfd closed.
3. Doing it on a "swap in" hook depends on when the "swap in" is called,
and how often, etc. It's not clear to me that there isn't a hole here. */

Relaxing on the m32r is tricky because of instruction alignment
requirements (4 byte instructions must be aligned on 4 byte boundaries).
The following relaxing opportunities are handled:
seth/add3/jl -> bl24 or bl8
seth/add3 -> ld24
It would be nice to handle bl24 -> bl8 but given:
- 4 byte insns must be on 4 byte boundaries
- branch instructions only branch to insns on 4 byte boundaries
this isn't much of a win because the insn in the 2 "deleted" bytes
must become a nop. With some complexity some real relaxation could be
done but the frequency just wouldn't make it worth it; it's better to
try to do all the code compaction one can elsewhere.
When the chip supports parallel 16 bit insns, things may change.
