This is a somewhat misleading fix, and if I understand things correctly,
it disables the special instructions "-mmx" etc. everywhere; but we should
keep them for x86_64. For instance, in the definition of zynaddsubfx we have
(add-after 'unpack 'remove-sse-flags-from-generic-target
(lambda _
(substitute* "src/CMakeLists.txt"
(("-msse -msse2 -mfpmath=sse") "")
(("-march=(athlon64|core2)" flag)
(string-append flag " -msse -msse2 -mfpmath=sse")))
#t)))))
I think this would warrant a bug report upstream, preferably by someone
who uses the package.
