[pulseaudio-discuss] make default resampler easier to set at configure time

[Daniel Kahn Gillmor]

I recently tried to get pulseaudio working on an little-endian arm
machine without an FPU.  Because pulse defaults to a resample-method of
speex-float-3, the resampling was incurring the kernel's softfloat
operations, which thrashed the CPU.

It seems to me that when building for a platform known to lack an FPU,
pulse should default to speex-fixed-3 instead of speex-float-3.  It
would be easier for distributors if this was an option to set when
configuring the pulseaudio build, rather than patching the source.

I've reported this originally as http://bugs.debian.org/696846, but it
seems like something that would be useful upstream.  Any thoughts on
this suggestion?
