And the buildbot flagged an issue on debian-i686:
https://builder.wildebeest.org/buildbot/#/builders/4/builds/110

readelf.c: In function ‘attr_callback’:
readelf.c:6261:27: error: format ‘%zx’ expects argument of type ‘size_t’, but argument 4 has type ‘Dwarf_Off {aka long long unsigned int}’ [-Werror=format=]
     error (0, 0, gettext ("no srcfiles for CU [%zx]"),
                           ^

Oops. Sorry about that. Fixed as attached.
