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.
