File fakeroot-1.21-hide-dlsym-error.patch of Package fakeroot

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.
