    [gdb/testsuite] Fix _selftest_setup on ppc64le-linux
    
    On ppc64le-linux, with gcc 7.5.0 and an O0 gdb build and test-case
    gdb.gdb/python-helper.exp, I get:
    ...
    (gdb) run ...
      ...
    Breakpoint 1, main (argc=12, argv=0x7fffffffea78) at .../gdb.c:30^M
    30        gdb_assert (is_main_thread ());^M
    (gdb) PASS: $exp: run until breakpoint at main
    ...
    
    But with an O2 gdb build, I run into:
    ...
    (gdb) run ...
      ...
    Breakpoint 1, 0x000000001003b438 in main (argc=12, argv=0x7fffffffea78) at \
      .../gdb.c:25
    25      {
    (gdb) FAIL: $exp: run until breakpoint at main
    ...
    
    The breakpoint is indeed set at address 0x1003b438:
    ...
    (gdb) break main^M
    Breakpoint 1 at 0x1003b438: file /space/vries/gdb/src/gdb/gdb.c, line 25.^M
    ...
    which is the local entry point:
    ...
    (gdb) disassemble main
    Dump of assembler code for function main(int, char**):
       0x000000001003b430 <+0>:     lis     r2,4606
       0x000000001003b434 <+4>:     addi    r2,r2,28416
       0x000000001003b438 <+8>:     mflr    r0
    ...
    
    And indeed, at that address, there's no "recommended breakpoint location":
    ...
    gdb.c:
    File name                Line number    Starting address    View    Stmt
    gdb.c                             25          0x1003b430               x
    gdb.c                             30          0x1003b454               x
    gdb.c                             37          0x1003b464               x
    ...
    
    So gdb behaves as expected.
    
    Fix this by updating the pass regexp to allow this type of gdb output.
    
    This fixes both test-case gdb.gdb/python-helper.exp and gdb.gdb/selftest.exp.
