USE flags

• audit - Enable support for Linux audit subsystem using sys-process/audit
• babeltrace - Enable dev-util/babeltrace support
• bpf - Enable support for eBPF features with dev-libs/libbpf
• caps - Use Linux capabilities library to control privilege
• clang - Enable builtin clang and LLVM support
• crypt - Add support for encryption -- using mcrypt or gpg where applicable
• debug - Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
• doc - Build documentation and man pages. With this USE flag disabled, the --help parameter for perf and its sub-tools will not be available. This is optional because it depends on a few documentation handling tools that are not always welcome on user systems.
