[linux-audio-user] Correct CFLAGS for libDSP and libConvolve?

I decided I'd really like to try these convolution reverbs that people on other platforms have been using for nearly 10 years, apparently.

So I grabbed jack_convolve, libconvolve, and libDSP.

It seems the're not autotools-enabled, so they don't just magically figure out the right set of CFLAGS. Unfortunately, I have no idea which to use. 

Building libDSP, I got stuff like:

gcc -march=pentium2 -mcpu=pentium4 -mmmx -O1 -ffast-math -fprefetch-loop-arrays  -Wall -Werror -g -D_REENTRANT -D_THREAD_SAFE -D_ISOC9X_SOURCE -D_GNU_SOURCE -DDSP_X86 -I.  -c X86.c
`-mcpu=' is deprecated. Use `-mtune=' or '-march=' instead.
X86.c: In function ‘dsp_x86_sse_addf’:
X86.c:479: error: unknown register name ‘xmm1’ in ‘asm’
X86.c:486: error: unknown register name ‘xmm1’ in ‘asm’
X86.c:486: error: unknown register name ‘xmm0’ in ‘asm’
X86.c: In function ‘dsp_x86_sse_add’:
X86.c:501: error: unknown register name ‘xmm1’ in ‘asm’
X86.c:508: error: unknown register name ‘xmm1’ in ‘asm’
X86.c:508: error: unknown register name ‘xmm0’ in ‘asm’
X86.c: In function ‘dsp_x86_sse_mulf’:

Ah, great.

The CPU I'm using to build the software and (hopefully) to run it, is this one:

Anyone want to venture a guess as to what GCC flags to use, or, better yet, how to cheat and make autotools tell me, even though this package doesn't use it?
