[gdb/testsuite] Fix gdb.dwarf2/dw2-using-debug-str.exp with cc-with-dwz-m
When running with target board cc-with-dwz-m, we run into:
...
(gdb) file dw2-using-debug-str-no-debug-str^M
Reading symbols from dw2-using-debug-str-no-debug-str...^M
(gdb) FAIL: gdb.dwarf2/dw2-using-debug-str.exp: file dw2-using-debug-str
...
With native, the .debug_str section is present in the
dw2-using-debug-str executable, and removed from the
dw2-using-debug-str-no-debug-str executable. When loading the latter, a dwarf
error is triggered.
With cc-with-dwz-m, the .debug_str section is not present in the
dw2-using-debug-str executable, because it's already moved to
.tmp/dw2-using-debug-str.dwz. Consequently, the removal has no effect, and no
dwarf error is triggered, which causes the FAIL.
The same problem arises with target board cc-with-gnu-debuglink.
Fix this by detecting whether the .debug_str section is missing, and skipping
the remainder of the test-case.
Tested on x86_64-linux.
