issue: git clone master branch, make failed and it reported error "immintrin.h: No such file or directory". compile environment is QEMU-user-based Arch Linux (MIPS R6) Docker image. Fix it with following patch can make successful.

Hmm, I remember that these includes have been an issue several times before. It's time to give up on looking for compiler defines and to add checks for the headers to configure.
