make: *** [release] Error 1

Start by reproducing LIBSQL_DIR=~/Workspace/database/libsql make release for the bottomless extension and inspect bottomless.c, where the missing macros, type, and WAL functions are referenced. Trace where those declarations are expected to come from, then verify that the release build produces bottomless.so without the reported compiler errors.
