Match the selftest output when captured_main is inlined 

In gdb.gdb/observer.exp, I see the following fail,

(gdb) break captured_main^M
Breakpoint 1 at 0x57e409: file ../../binutils-gdb/gdb/main.c, line 492.^M

(gdb) FAIL: gdb.gdb/observer.exp: run until breakpoint at captured_main

looks the test sets breakpoint on captured_main, and expects program
stops at captured_main.  However, program stops at the place where
captured_main is called, because captured_main is inlined,

 <1><8519e3>: Abbrev Number: 58 (DW_TAG_subprogram)
    <8519e4>   DW_AT_name        : (indirect string, offset: 0x880d3): captured_main

    <8519f0>   DW_AT_sibling     : <0x851c01>

The test passes if I build GDB with '-O0 -g3', because captured_main
isn't inlined.  This patch is to match the output when captured_main
is inlined.
