One cheap option is to simply link the libraries static into your
application with the ld option --static.


If you're using glibc as your c library you can export the
variable LD_PROFILE=[libraryname] to tell the dynamic linker to profile the
shared library with this name...


Best see the ld.so man pages, like i.e.
