Avoid timeouts in gdb.compile
PR compile/29541 points out that some of the C++ tests in gdb.compile
will time out when the glibc debuginfo is installed. This was
interfering with my hacking on gdb by making test runs extremely long,
so I looked into it.
Internally the bug seems to be that gdb tries to convert multiple
symbols named "var" via the compiler interface; one such symbol (I
didn't track it down too far) causes the C++ compiler plugin to crash.
Unfortunately, the crash is reported as a timeout, as the gdb side of
the plugin simply hangs. This seems like a bug in the plugin RPC
mechanism and, worse, apparently when I wrote this stuff I didn't
really consider error reporting very much at all, so gdb can't really
detect failures in the first place.
Anyway... this patch works around the timeout by compiling a simple
test that should provoke this bug, and then using "untested" if it
notices a GCC crash.
