v0.3.4 build failure in osx

[isuruf]

Building for DYNAMIC_ARCH fails with,

../kernel/x86_64/dgemm_kernel_4x8_skylakex.c:872:5: error: invalid alignment value
                        ".align 32\n"

Let me know if you need more info on the build environment.

Looks like a return of the OSX ".align vs .p2align" issue of #1470 (i.e. these should probably be converted to ".p2align 5")

We (Numpy) just hit this too:

You can quickly avoid building the implicated code by setting NO_AVX512=1 and mapping skylakex to haswell.

Yeah that is the beauty of this project - any small oversight at release time is going to hit a lot of projects. Fix in place now.

Thanks for fixing so quickly.

Thanks for fixing this.
