Bug report
Bug description:
2950bc5 inadvertently caused -pydebug to no longer be appended to pybuilddir.txt.
Since the WASM build scripts look for it on the build-python's pybuilddir.txt to decide whether or not to configure the host with --with-pydebug, they stopped honoring the build-python configuration.
I noticed this when I unintentionally fixed it in GH-131761, which uncovered another issue, GH-130397.
