Subject: [PATCH] package/patch: add optional support for attr

When attr was compiled before, patch will use it as optional dependency:

$ output/host/usr/bin/x86_64-linux-readelf -a output/target/usr/bin/patch | grep NEEDED
 0x0000000000000001 (NEEDED)             Shared library: [libattr.so.1]
 0x0000000000000001 (NEEDED)             Shared library: [libc.so.1]
