SVML unavailable in numba v0.63.1 #10404

Description

@jack-mcivor

I was following the instructions to use SVML here https://numba.readthedocs.io/en/stable/user/performance-tips.html#intel-svml, but cannot get SVML operational. Is there something I'm missing?

Steps:

# using uv 0.9.24 on a blank directory
uv init --python 3.13
uv add numba==0.63.1 intel-complr-lib-rt==2025.3.1 pip
# installs numba==0.63.1, llvmlite==0.46.0, numpy==2.3.5, intel-cmplr-lib-rt==2025.3.1
# pip is needed for `numba -s` to introspect the environment
uv run numba -s
