If that is the case, the musl libc vs. glibc decision should be based on `$host_os` rather than `$build_os` as the former is based on autoconf's `AC_CANONICAL_HOST` macro[^2] which refers to the target platform that might differ from the build platform in case of cross-compilation.\r\n\r\nI'm creating this as a separate issue concerning a particular problem, but I think this also contributes to existing discussion in  https://github.com/python/cpython/issues/87278 .\r\n\r\n[^1]: \"internal configure error for the platform triplet, please file a bug report\"\r\n[^2]: https://www.gnu.org/software/autoconf/manual/autoconf-2.68/html_node/Canonicalizing.html\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-107221\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/autobakterie","@type":"Person","name":"autobakterie"},"datePublished":"2022-08-10T15:43:31.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/95855/cpython/issues/95855"}
