Move the implementation of the fix from Makefile.rules to Makefile. This
ensures that it is only checked on a top-level rebuild, and not in every
single subdirectory. This removes some annoying messages from the build and
numerous executions of config.status if the .in file changes but not
substantively enough to cause the .h file to be modified by config.status.

to codegen this: float foo() { return 1.245; }

into this:

_foo:
        lis r2, ha16(.CPI_foo_0)
        lfs f1, lo16(.CPI_foo_0)(r2)
        blr

instead of this:

_foo:
        lis r2, ha16(.CPI_foo_0)
        lfs r2, lo16(.CPI_foo_0)(r2)   <-- ouch
        or f1, r2, r2                  <-- ouch
        blr

Emit the indcall sequence as:

mtctr inreg
mr R12, inreg
btctr

If inreg and R12 aren't coallesced, this reduces the odds of having the mtctr
and btctr in the same dispatch group.  :)
