`make check` fails in VPATH build

Hello Serveez,

If I configure and build serveez 0.2.1 from a directory other than
top_srcdir, I get an error when running `make check`:

Backtrace:

7 out of 8 tests fail in this same way.

Where /tmp/serveez-0.2.1/build is the directory that configure was run
in.  If I configure and build in /tmp/serveez-0.2.1, then all tests
pass.
