--- Comment #1 from Mark Wielaard <mark at klomp dot org> ---
That is odd, this configure.ac snippet should for build-ids on:

# We really want build-ids. Warn and force generating them if gcc was
# configure without --enable-linker-build-id
AC_CACHE_CHECK([whether the compiler generates build-ids], ac_cv_buildid, [dnl
AC_LINK_IFELSE([AC_LANG_PROGRAM()],[ac_cv_buildid=yes; $READELF -n
conftest$EXEEXT | grep -q NT_GNU_BUILD_ID ||
ac_cv_buildid=no],AC_MSG_FAILURE([unexpected compile failure]))])
if test "$ac_cv_buildid" = "no"; then
        AC_MSG_WARN([compiler doesn't generate build-id by default])
        LDFLAGS="$LDFLAGS -Wl,--build-id"
fi
