There is some mention on the web of an environment variable you can
set: LD_PROFILE=<libname>

These pages seem relevent:
http://sourceware.org/ml/binutils/2002-04/msg00047.html
http://www.scit.wlv.ac.uk/cgi-bin/mansec?1+gprof

It's wierd how some man pages for gprof describe this feature, but the
one on my local system doesn't mention it.
