For some strange reason this hasn't hit the Changelog yet but I note that in blfs r11.3-1261, on the page https://www.linuxfromscratch.org/blfs/ view/svn/multimedia/alsa-utils.html, there is a fix. I can confirm that it works.
----- quote from alsa-utils.html
This package provides its own implementation of strlcpy and strlcat functions.
But they are provided by Glibc-2.38 now, so we need to remove the custom implementation to avoid a conflict with the Glibc header:
