ok, all good ideas.

I have made the changes to configure.in and various Makefile.am's.
I added the cpu checking (based on $host_cpu) and an option to
disable all asm optimizations (--disable-asm-optimizations).

but since I'm not too saavy with autoconf/automake I'll ask for a
little bit more help.  I think the only non-functional part left is
that automake doesn't support source files that are in subdirectories,
relative to Makefile.am(?)  the layout in src/libFLAC/ is that all
asm sources will go under a 'cputype' directory (e.g.
src/libFLAC/i386/ for x86 sources).  having to put them all in
src/libFLAC/ would be a mess later.  can you guys take a look and
advise?

Josh
