Description of problem:
The subversion testsuite which is being run during rebuild fails if the package is being rebuilt by the root user.
The testsuite should either be fixed or rebuild as root discouraged and the testsuite problem workarounded.

Version-Release number of selected component (if applicable):
subversion-1.7.14-1.el7.src.rpm

How reproducible:
always

Steps to Reproduce:
1. su -
2. yumdownloader --source subversion
3. (install the missing dependencies)
4. rpmbuild --rebuild subversion*src.rpm

Actual results:
There was 1 failure:
1) testBasicLocking(org.apache.subversion.javahl.BasicTests)junit.framework.AssertionFailedError: file should be read only now expected:<false> but was:<true>

FAILURES!!!
Tests run: 54,  Failures: 1,  Errors: 0

make: *** [check-javahl] Error 1


Expected results:
the build fails more gracefully and suggests a way to workaround (to disable the tests)

Additional info:
for example, the mariadb spec has this:

# fail quickly and obviously if user tries to build as root
%if %runselftest
        if [ x"`id -u`" = x0 ]; then
                echo "The mariadb's regression tests may fail if run as root."
                echo "If you really need to build the RPM as root, use"
                echo "--define='runselftest 0' to skip the regression tests."
                exit 1
        fi
