Hey Alan!
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:
echo '' > alsactl/init_sysdeps.c
----- end of quote
Life is good,
Maurice
