[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. PR testsuite/30648 Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=30648
