            Log:
            Add 'tests' definition.

Defining this option will iimit the tests performed with the "--with testsuite"
option:

$ rpmbuild -bb --with testsuite --define 'tests "gdb.base/break.exp gdb.dwarf2/*.exp"' \
   gdb.spec

The above will build the RPM with testing, but it will only test the listed tests
(just as if they were passed to TESTS="gdb.base/break.exp gdb.dwarf2/*.exp").
