Fix gdb.base/infcall-nested-structs-c++.exp with Clang
gdb.base/infcall-nested-structs-c++.exp failed to build using Clang
with many variations on the following error:
gdb compile failed, /gdbtest/src/gdb/testsuite/gdb.base/infcall-nested-structs.c:207:46:
warning: self-comparison always evaluates to true [-Wtautological-compare]
This commit builds this testcase with -Wno-tautological-compare when
using Clang, to avoid this failure.
gdb/testsuite/ChangeLog:
* gdb.base/infcall-nested-structs.exp.tcl: Add
additional_flags=-Wno-tautological-compare for C++
tests when compiling using Clang.
