This patch does a lot more than what is described.
It seems adding support for FreeBSD.
For testing OS, please use #ifdef RTE_EXEC_ENV_*

Well, isn't FreeBSD already supported?
Even https://www.dpdk.org/ mentions supporting FreeBSD.

Yes it is supposed to be supported.
But why are you adding all this code for PPC?
It doesn't seem to be all related to clang only.
PS: please do not top-post.
