- Subject: [PATCH] macos: somehow allow building with a target below 11.0
- While building for macOS older than 11 in Apple Silicon makes no
- sense, some build systems lack the flexibility to set a target per
- architecture while aiming to support multi architecture binaries.
- Allow an option in those cases by using the slower runtime checks
- if the toolchain allows it.
- Fixes: PCRE2Project/pcre2#109
