The local.conf.sample does contain this section:

# Uncomment these to build a package such that you can use gprof to profile it.
# NOTE: This will only work with 'linux' targets, not
# 'linux-uclibc', as uClibc doesn't provide the necessary
# object files.  Also, don't build glibc itself with these
# flags, or it'll fail to build.
#
# PROFILE_OPTIMIZATION = "-pg"
# SELECTED_OPTIMIZATION = "${PROFILE_OPTIMIZATION}"
# LDFLAGS =+ "-pg"

This seems to do the work for the complete image.

But is it possible to enable profiling for selected libs and/or binaries only?
