Unable to link on Apple M1

[matthagan15]

I have installed intel mkl and verified it can be found with pkg-config, as running pkg-config --variable=prefix mkl-static-lp64-seq results in the output /opt/intel/oneapi/mkl/latest/lib/pkgconfig/../.. . However, when running a barebones binary setup with the following lines in my Cargo.toml:

ndarray = {version = "*", features = ["blas"]}
ndarray-linalg = {version = "*", git="https://github.com/matthagan15/ndarray-linalg.git", branch="stable_expm"}
blas-src = {version = "*", features = ["intel-mkl"]}

I get the following output when trying to build a tester binary:

error: linking with `cc` failed: exit status: 1
