`generate-installer` refuses a macOS archive, so the last step of the pipeline cannot succeed there. Left to fail on its own it does so only after a full source build has been spent, so check the platform up front, like the entry name guards above it.

# Summary: Build a Python version and package it as an installable binary
|
|
#
|
|
# Usage: pyenv binary build <version>:<entry> --archive-url <url>
|
|
#
|
|
# Builds <version> from source under the separate name <entry>, packages the
|
|
# result with `pyenv binary save', then emits a python-build definition for
|
|
# it with `pyenv binary generate-installer'. The archive, metadata and
|
|
# definition are written to the current directory, named after <entry>.
|
|
#
|
|
# <version> A version `pyenv install' knows how to build.
|
|
# <entry> The name to build under and to install the binary
|
|
# as, e.g. `3.13.14-debian-12'. Keeping it distinct
|
|
# from <version> lets the binary sit alongside a
|
|
# normal source install of the same version.
|
|
# --archive-url <url> Where the archive will be hosted; the definition
|
|
# downloads it from <url>/<archive-name>.
