ppc64le and intrinsics

[fitzsim]

ggml.c fails to compile on Debian ppc64le, GCC 11, with:

ggml.c:135:10: fatal error: immintrin.h: No such file or directory 135 | #include <immintrin.h>

If I comment out that line, the build succeeds and the output binary works.

Should be better than commenting it out:

Looks like my patch builds, but doesn't actually use intrinsics :/
