According to the latest bulk build report, building csound fails on powerpc:

In file included from /usr/obj/ports/csound-7.0.0beta13/csound-7.0.0-beta.13/OOps/pffft.c:107:
/usr/lib/clang/19/include/altivec.h:13:2: error: "AltiVec support not enabled"
   13 | #error "AltiVec support not enabled"
      |  ^
/usr/lib/clang/19/include/altivec.h:50:19: error: unknown type name 'vector'
   50 | static __inline__ vector signed char __ATTRS_o_ai vec_perm(


The diff below should "fix" this by disabling altivec on powerpc.
(I have not tested it on powerpc)

ok?
