This should not take an arch parameter, so it can properly be used
 as a fallback for accelerated versions which do not.
This patch instead provides a separate version which can call
 accelerated helpers for platforms that have taken that approach.

The patch in 76e831d9 got us most of the way there, but
 out-of-tree builds required a second Makefile.am rule, which was
 missing @ARM2GNU_PARAMS@.
Also, the arm2gnu.pl was terminating argument processing on any
 argument beginning with --, rather than an argument that was just
 -- by itself (as is the normal convention in GNU programs).
That meant it never saw the --apple flag even when it was passed.

Thanks to Jonathan Lennox for the report and for testing.

Saves 0.6% for 64 kb/s and 1.8% for 128 kb/s when decoding on arm7tdmi.

This should prevent extreme dynalloc behaviour in cases where some
bands are heavily attenuated.

Also minor C89 fix for the previous commit
