The branch main has been updated by andrew: URL: https://cgit.FreeBSD.org/src/commit/?id=ceefd491c7f0490515fadca2f3740cb24e3f449e commit ceefd491c7f0490515fadca2f3740cb24e3f449e Author: Andrew Turner <andrew@FreeBSD.org> AuthorDate: 2023-10-20 15:45:06 +0000 Commit: Andrew Turner <andrew@FreeBSD.org> CommitDate: 2023-10-20 15:45:06 +0000 tools/build: Support building with glibc 2.38 Ubuntu 23.10 uses glibc 2.38. This adds strlcpy and strlcmp so we need to remove them from the cross build environment.
