Subject: [PATCH 1/3] allow native cpu detection when building with clang
function was disabled for non-gcc5 in:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=b587c12551143c14f023860a1dbdf7316ae71f27;hp=43096b526a9f23008b9769372f11475ae63487bc
clang can build it correctly and this should probably be a feature test
