Without the change parallel installs fail as:
...-binutils-2.40/bin/ld: cannot find ./.libs/libircd.so: No such file or directory
collect2: error: ld returned 1 exit status
make[4]: *** [Makefile:634: solanum] Error 1
Previously this defaulted to the default MOTD in the solanum source
tree, and I don't want my friends to laugh at me. Includes a patch to
the tests to ensure that the MOTD is actually set.
This replicates the fix done in #109705 (solanum is a fork of charybdis,
so they share fundamental logic for this).
