The test directive dg-additional-sources specifies one or more
additional files to use for a test; they are added to the compile line
for the main test file.

Each .exp file uses a glob pattern to find test names to pass to
dg-runtest.  See gcc.dg/special/special.exp, which uses a pattern to
omit the names of additional source files in that directory.  Another
(untested and rather ugly) possibility is to add

  { dg-skip-if "" { *-*-* } { "*" } { "" } }

to the additional files so they'll be treated as skipped tests.
