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
