[gdb/testsuite] Fix gdb.dwarf2/dw2-dir-file-name.exp for ppc64le
In commit cd919f5533c ("[gdb/testsuite] Fix
gdb.dwarf2/dw2-dir-file-name.exp"), I made gdb.dwarf2/dw2-dir-file-name.exp
independent of prologue analyzers, using this change:
...
- gdb_breakpoint $func
+ gdb_breakpoint *$func
...
That however caused a regression on ppc64le. For PowerPC, as described in the
ELFv2 ABI, a function can have a global and local entry point.
Setting a breakpoint on *$func effectively creates a breakpoint for the global
entry point, so if the function is entered through the local entry point, the
breakpoint doesn't trigger.
Fix this by reverting commit cd919f5533c, and setting the breakpoint on
${func}_label instead.
Tested on x86_64-linux and ppc64le-linux.
