Hello,

this patch implements support for powerpc64le architecture on FreeBSD. Since we don't have powerpcle (32-bit), I did not add support for powerpcle here. This remains to be changed if there is powerpcle support in the future.

Patch implements similar endian detection to what linux64.h uses.

Would it be ok to backport it to at least GCC 10?
