This version adds extra tests for HAVE_XCOFF_DWARF_EXTRAS. I placed
the default in dwarf2out.c instead of defaults.h.
Because eh_frame is internal to GCC with its own section, I emit the
length, but inhibit the length for AIX debug_frame section.
This allows DWARF debugging to work on older AIX 7.1 systems within
the limitations of the available sections. It also allows it to build
and test on a wider variety of AIX 7.1 systems.
I also changed the TLS decorations to use a switch statement, as suggested.
Thanks, David

I see a build failure on powerpc64le-linux-gnu:

The above ChangeLog entry doesn't mention the patch to configure.ac and the
regeneration of configure, but it is included in the commit message. It looks
like that gcc/configure was manually fixed without fixing gcc/configure.ac.
Committing as obvious (although I see some whitespace changes with an unmodified
autoconf2.64 downloaded from ftp.gnu.org).
