This patch is the result of a discussion on lldb-dev, see
http://lists.llvm.org/pipermail/lldb-dev/2018-January/013111.html for
background.
For each test (should be eventually: each test configuration) a
separate build directory is created and we execute
make VPATH=$srcdir/path/to/test -C $builddir/path/to/test -f $srcdir/path/to/test/Makefile -I $srcdir/path/to/test
In order to make this work all LLDB tests need to be updated to find
the executable in the test build directory, since CWD still points at
the test's source directory, which is a requirement for unittest2.
Although we have done extensive testing, I'm expecting that this first
attempt will break a few bots. Please DO NOT HESITATE TO REVERT this
patch in order to get the bots green again. We will likely have to
iterate on this some more.

gcc emits DW_LANG_C89 even if we specify -std=c99 during compilation.
Since this isn't an lldb bug, but just the way the compiler happens to
be implemented, I teach the test to expect this situation correctly.
