An addendum:
The package currently builds at debhelper compat level 11. If this is
increased to 13, the build fails at the dh_dwz step. Build log excerpts
are below.
The build uses symbol_level=0 in debian/rules (which causes -g0 to be
passed to the compiler). If this is set to 1, dh_dwz succeeds. (If this
is set to 2, dh_dwz fails with a different error.)
Alternately, DEB_BUILD_OPTIONS=nostrip works around the issue. However,
it results in a number of "Unrecognized form" warnings from objdump(1)
and readelf(1), for some reason.
(I hope this is useful information, as this issue is likely to crop up
in the Debian build sooner or later.)
