[RFA] testsuite gdb.base/expand-psymtabs: ensure code is generated for the expected source line

Does you compiler also attach the epilogue code to the opening brace
as well.  With GCC, the epilogue is attached to the closing brace,
and so breaking on the empty line causes the breakpoint to be inserted
at the beginning of the epilogue.

Seems harmless in any case, and in fact, the original version of
the testcase when submitted included a function call at this location.
The reason why it was removed was that it was calling an IO function,
which is a no-no if we can avoid it (so that the testcase can be run
on targets that do not provide these routines).

OK to check in.
