contrib: Fill in HOST{CC,CFLAGS,CXX,CXXFLAGS} in test_installed

Browse Source 
gcc/Makefile.in since my r0-60234 change fills in HOSTCC and HOSTCFLAGS
in site.exp and since r8-671 also HOSTCXX and HOSTCXXFLAGS.
If those variables aren't set, we get errors like:
/usr/src/gcc/contrib/test_installed --without-g++ --without-gfortran --without-objc struct-layout-1.exp
...
ERROR: tcl error sourcing /usr/src/gcc/gcc/testsuite/gcc.dg/compat/struct-layout-1.exp.

(similarly in g++ or gfortran) struct-layout-1.exp.  One doesn't need to
test specially for just struct-layout-1.exp alone, just not using any arg
will trigger it as well, just later.

The following patch fills it in as cc and c++ with empty flags to compile
those, I believe that is what e.g. make uses by default, so it should be a
reasonable default.  We IMHO shouldn't default to GCC_UNDER_TEST because
that might be a cross-compiler etc.

	* test_installed: Fill in HOSTCC, HOSTCXX, HOSTCFLAGS and
	HOSTCXXFLAGS.
