You'd normally just invoke commands for updating sources as run_target()s, not
custom targets. Or generate them in the build tree via custom_target() and
then copy to the source tree via a run_target().

For this case I think it'd suffice to add a run target that does something
like
make -C ~/src/postgresql/src/test/ssl/ -f ~/src/postgresql/src/test/ssl/sslfiles.mk sslfiles OPENSSL=openssl

obviously with the necessary things being replaced by the relevant variables.

sslfiles.mk doesn't depend on the rest of the buildsystem, and is a rarely
executed command, so I don't see a problem with using make to update the
files. At least for a long while.
