Have a look at the SELF Makefile... you should run

$(CROSS_PREFIX)strip --remove-section=.note --remove-section=.comment *.so

on all libraries on the trarget filesystem.

And for really limited cases there is ulibc, the  library  optimizer,
etc.

Ill-chosen abstraction is particularly evident in the design  of  the
ADA  runtime  system.  The  interface to the ADA runtime system is so
opaque that it is impossible to model  or  predict  its  performance,
making it effectively useless for real-time systems.
