Does HP/UX 11.11 use ELF?  If so, I guess we need a configure test to see
whether the linker supports the --build-id option.  If it doesn't, I guess we
need to skip the debuginfo tests.

The 64-bit target uses ELF.

Currently, HP ld is the only working linker and it doesn't support the
--build-id option.  GNU
ld has problems with shared library support.

It appears the --build-id issue is fixed by the change.

But there's still a lto issue breaking make check:

--- Comment #6 from Ian Lance Taylor <ian at airs dot com> ---
The LTO problem seems like a different problem, and doesn't seem related to
libbacktrace.

If LTO doesn't work HP/UX, do you have a simple test that the configure script
could run to see whether it works?

Will investigate.
