[Darwin, Objective-C] Don't prepend a sysroot for the gnu-objc headers.
Darwin is able to use two runtimes for objective-c; the
default is its native NeXT runtime, but also it can build
code using the gnu-runtime. In order to do this, we have to
be able to find the gnu-runtime headers (which are installed
into the compiler's tree).
The process to do this was erroneously prepending the sysroot
to this when a sysroot is in force. The gnu-runtime headers have
never been installed in a Darwin (MacOS) SDK so we must make
sure that they are found local to the compiler.

The recursive_init_error class is defined in a header, with an inline
constructor, but the definition of the vtable and destructor are not
exported from the shared library. With -fkeep-inline-functions the
constructor gets emitted in user code, and requires the (non-exported)
vtable. This fails to link.
As far as I can tell, the recursive_init_error class definition was
moved into <cxxabi.h> so it could be documented with Doxygen, not for
any technical reason. But now it's there (and documented), somebody
could be relying on it, by catching that type and possibly performing
derived-to-base conversions to the std::exception base class. So the
conservative fix is to leave the class definition in the header but make
the constructor non-inline. This still allows the type to be caught and
still defines its base class.
