Speex dev - May 2005 - Cross-compiling with Cirrus Logic MaverickCrunch support

ok, I'll try both configurations.

Unfortunately the core is 920T, thus it does not implement ARMv5
instruction set.
As soon as I have a working MaverichCrunch-enabled tool chain, I'll
post the results.

Hi Jean-Marc,

I have the following problem when cross-building speex 1.1.7 with
MaverickCrunch support. To add this support I had to define CPPFLAGS as 
follows:

export CPPFLAGS='-mcpu=ep9312 -mfix-crunch-d1'

but it seems libtool does not like it, while the object files are
compiled fine:

...

You should set CFLAGS instead (or as well).

It's ld that complains, actually.  Not _everything_ is libtool's fault
(and this is pilot error anyway) ;-)
