On PowerPC, the compiler will tag object files with whether they use hard or soft float FP ABI and whether they use 64 or 128-bit long double ABI. On systems with 64-bit long double ABI, a tag will get emitted whenever a double is used, as on those systems a long double is the same as a double. This will prevent linkage as other files are being compiled with hard-float. On ppc64, this code will never actually get used for the time being, as the only currently existing hardware using it are the Renoir APUs. Therefore, until this is testable and can be fixed properly, at least make sure the build will not fail.
