Synchronet build process not completing

Building Synchronet on Ubuntu 20.04 using the latest development branch of Synchronet as of 3/22/22. The process is failing as follows:

Linking gcc.linux.x64.lib.release/libwebsrvr.so Linking gcc.linux.x64.exe.release/sbbs /usr/bin/ld: gcc.linux.x64.lib.release/libwebsrvr.so: undefined reference to `strlcpy' collect2: error: ld returned 1 exit status make: *** [GNUmakefile:151: gcc.linux.x64.exe.release/sbbs] Error 1

I've tried doing a "make clean" prior to running "make RELEASE=1 symlinks setcap" and still the same result.
