+Description: Hide error from dlsym()
+ dlsym(), starting in glibc 2.24 actually reports errors. In our case,
+ we try to get ACL functions which are not in the glibc. This causes
+ failures in test suites, so hide those messages for non-debugging
+ purposes for now. It also makes the build logs annoying to read.
