ok gkoehler@
The compiler inlines the amd64 cpu instruction for sqrt, but one can
reproduce the error on amd64 by,
$ make COPTS=-fno-builtin-sqrt
powerpc64 clang inlines the instruction "fsqrt", but macppc clang calls
sqrt() and needs libm. This is because llvm believes that the G5 has
"fsqrt" but G4 and G3 don't have "fsqrt"; and the default target cpu in
powerpc64 clang seems to be the G5. --George
