I'm currently running a couple of bootstraps (Solaris 10, 11.3, 11.3
with as/ld and gas/ld on SPARC, Solaris 10 with as/ld, Solaris 11.3 with
gas/ld, Solaris 11.4 with gas/gld on x86) with a tree that has

        https://gcc.gnu.org/ml/gcc-patches/2018-02/msg00624.html

applied to check if that fixes either or both of this PR and PR
debug/84319.

Right now (using either the native assembler or gas 2.30) I find that
neither of HAVE_AS_DWARF2_DEBUG_LINE and HAVE_AS_DWARF2_DEBUG_VIEW are
defined with as, but both with gas.
