[gdb/testsuite] Fix gdb.gdb/python-helper.exp with -O2 -flto=auto and gcc 7.5.0
With a gdb build with -O2 -flto=auto using gcc 7.5.0, I run into:
...
(gdb) ptype global_c^M
^M
Thread 1 "xgdb" hit Breakpoint 3, \
_Z12c_print_typeP4typePKcP7ui_fileii8languagePK18type_print_options () at \
gdb/c-typeprint.c:175^M
175 {^M
(outer-gdb) FAIL: gdb.gdb/python-helper.exp: hit breakpoint in outer gdb again
...
This is a problem with the debug info, which marks the CU containing the
function declaration as C rather than C++. This is fixed in gcc 8 and later.
Work around this compiler problem by allowing the mangled name.
Tested on x86_64-linux.
