Name both build strings (conda-forge openblas openmp/pthreads style), down-prioritize relaxed_simd, and bump the build number to 3.
Bump the build number as the package version string is unchanged.

openblas(fromopenblas-experimental)0.3.35.dev0(build 3), snapshot of OpenMathLib/OpenBLASdevelop@ b4100afBuild Notes
Add a second WASM build variant for OpenBLAS #6020 relaxed SIMD, following the conda-forge OpenBLAS named-build-string pattern (
openmp/pthreads):openblas_wasm_relaxed_simd0simd128_h…_31relaxed_simd_h…_3down_prioritize_variant: 1Users select explicitly, for example:
WASM_RELAXED_SIMDis passed through to Make from the variant. The relaxed-SIMD module will not instantiate on engines without the feature (notably shipping Safari / JavaScriptCore); see OpenBLAS docs.The package version string is unchanged, so the build number is bumped to 3.
