If you have a broken libtool (like almost everyone since there is no
release since the fix was pushed), you have to force extra flags:
LDFLAGS="-lasan" when running configure. This fixes the asan link
errors, but this also add this flags for configure tests like iconv.

So that is why there is no subtitles with my ASAN build...

Could we find a way to make every one happy  ?
