They have been installed by the OS (from the initial installation
media or subsequent update processes), as the /usr/lib directory
is reserved for OS files (like /usr/local/lib is for 3rd party
libraries).

Hmmm... I always thought that would be the default (no profiling libs
being built and installed). But according to "man src.conf", the
setting's name is WITHOUT_PROFILE, not NO_PROFILE.
