Note that a $PATH search excludes shared libraries, which can also
carry <sys/sdt.h> markers.  Adding /usr/lib* in more than doubles the
work, then there's /usr/libexec etc.

To find all system libraries, we can use ldconfig.

$ ldconfig --print-cache

shows what dynamic libraries will be loaded. On my own laptop (running
ubuntu13.04) shows ~1000 libs.

Thank you,


Ah! that seems nice... will save a lot of time!
