[PlanetCCRMA] Error compiling Jack on X86_64

[Janina Sajka]

I suppose it's arugable whether I'm a masochist, but I do have a Opteron
box here and I'm trying to compile some of the CCRMA packages for this
platform. So far, alsa-driver/kernel-module and libsndfile have
compiled, but jack fails with an error that makes me want to say,
"Duh-uh?" ...

cc1: error: bad value (x86_64) for -march= switch
cc1: error: CPU you selected does not support x86-64 instruction set

To me, a most inexpert coder, this looks like a trivial oversight
somewhere in the code. march and mcpu are clearly unmatched. But, I'm
also thinking I shouldn't go on appearances. So, mindful that the Jack
FAQ notes issues with 2.6.7 kernels (which mine is, from the Fedora
development tree), is this something likely to be fairly easy to
resolve? Or shall I wait on the experts to resolve a larger tangle than
I currently comprehend?
