Conda-forge binaries (pixi-managed Python, pip manylinux wheels, etc.)
expect /lib64/ld-linux-x86-64.so.2 and dynamically link against libc
at hardcoded FHS paths that don't exist on NixOS. Without nix-ld,
`pixi install` fails during PyPI source builds with:
build dispatch initialization failed: failed to query interpreter
in instantiated prefix
because pixi can't invoke the prefix's Python to read interpreter
metadata. Enabling nix-ld with stdenv.cc.cc.lib and zlib provides
the FHS-style loader and core libraries these tools assume.
