Ramsay JonesCommit 817151e61a ("Rename safe_strncpy() to strlcpy().", 2006-06-24) added the NO_STRLCPY make variable to allow the conditional use of the gitstrlcpy() compat function on those platforms which didn't provide the 'standard' strlcpy() function.
Recently, in the summer of 2023, the strlcpy() and strlcat() functions were added to the glibc library (v2.38), so some of the more up-to-date Linux distributions no longer need to set NO_STRLCPY. For example, both Ubuntu 24.04 LTS and RHEL 10 beta have glibc v2.39. However, several distributions, which are still within their support window, have an earlier version and must still use the 'compat' version of strlcpy().
If the meson or autoconf build systems are used on newer platforms, then they will be configured to to use strlcpy() from glibc, whereas the make build will always choose the 'compat' function instead. Add a note to the config.mak.uname file, in the Linux section, to prompt make users to override NO_STRLCPY in the config.mak file, if appropriate.
