For the GCC packaging, I started using the symbols helper for the
sanitizer libraries.  However, these are not the only libraries, and
other libraries are not handled by the symbols helper.

A batchpatch call stops with the first symbols file, that is not handled
by symbolshelper:

pkgkde-symbolshelper: error: input symbol file template must \
	have 'SymbolsHelper-Confirmed' header
pkgkde-symbolshelper: error: libgphobos7 patching FAILED. \
	Will NOT continue.

For me, that is expected, and the tool should continue with other
runtime libs.  For now, you have to edit all log files to remove these
dpkg-gensymbol calls for these libraries.

So either skip symbols files without such a header, or only fail at the
end, and keep going with other symbols files.
