gdb.trace: Use manually-defined start labels in unavailable-dwarf-piece.exp
On powerpc64, foo/bar point to a function descriptor, not to function code.
Since there are no global labels pointing at the actual function code,
let's make our own.
Regression-tested on x86_64.
gdb/testsuite/ChangeLog:
* gdb.trace/unavailable-dwarf-piece.c (foo): Add foo_start_lbl label.
(bar): Add bar_start_lbl label.
* gdb.trace/unavailable-dwarf-piece.exp: Use foo/bar_start_lbl instead
of foo/bar for emitting DWARF and tracing.
