It's probably a side-effect of the fact my userland was built with
DEBUG_FLAGS='-g' and this was compiled without a full buildworld.
Thus the binaries I compiled used debugging versions of the libs
from /usr/lib but their own source was built with DEBUG_FLAGS=''.

Nevermind about the binary difference in sizes; it's probably a local
build-related issue.  It's good to know that rescue doesn't grow a
lot anyway :)
