Drop remove.ldconfig.call.patch, as it's easier to just set LDCONFIG=true.
Pass uname=GNU via the documented configure option instead of undocumented
environment variable.
Rename zlib-1.2.11/ to just zlib/ as we don't ship multiple versions.
Send ldflags-tests.patch upstream and update Upstream-Status.
