Enable ppc64le (#9)

* Enable ppc64le

This should be possible now that support for ppc64le has been
re-enabled for libgdal
conda-forge/gdal-feedstock#968

* MNT: Re-rendered with conda-build 24.5.1, conda-smithy 3.37.1, and conda-forge-pinning 2024.07.31.04.56.44

* strip architectures from flags for native builds

* don't depend on leading whitespace in sed-replacement
