With current configure some capabilities tests for in-tree gas and ld are based
only on version (that's wrong, because for COFF many features (TLS) isn't
supported), other tests require version and ELF target (again wrong, because
some features (dwarf2) supported of COFF too)
To workaround this, I've patched configure to make real tests on gas and ld
even for combined tree as toplevel makefile build gas, ld and binutils before
running gcc configure.
But for real fix we need to patch autoconfigure files.
