S390, the dw2-dir-file-name test case fails in the first
gdb_continue_to_breakpoint. Indeed, the breakpoint is now placed into
the alignment gap *before* the actual function.
This happens because the test case declares the respective "*_start"
symbol as a "loose" label before the function definition, and the
compiler inserts the alignment between that label and the function
itself.
The "*_start" symbols were only necessary because FUNC made the
function static. The fix makes the functions extern instead, thus
making the "*_start" labels unnecessary.

Pedro Alves <palves@redhat.com>
* gdb.dwarf2/dw2-dir-file-name.c (FUNC): Remove "*_start" symbol.
Make "name" extern.
* gdb.dwarf2/dw2-dir-file-name.exp (out_cu, out_line): Replace
references to ${name}_start by references to ${name}.
