Subject: [PATCH] [build] Add optional build-id

Build-ids are required for doing certain kinds of performance tracing.
For example build-ids let Linux perf find the correct objects and
transfer them to other machines via "perf archive".

This adds an option to add -Wl,--build-id to the linker. It can be
enabled by passing -Dbuild_id=true to meson or --build-id to
package-release.sh.
