Certainly try it, but there seem to be very few cases where this is
actually worthwhile, and in most cases it's already been done for you.
For example, OpenSSL, mplayer, etc.

For the Debian sources, you can often get away with just setting the CFLAGS
(for gcc) and CXXFLAGS (for g++) environment variables.  A more robust
solution might be to install pentium-builder, which (AIUI) wraps gcc
entirely, so no environment variable hackage is needed.

The compilation of Debian packages is controlled by the debian/rules
file.  You can certainly edit that to enable anything you want, but I
think the pentium-builder package would be a better solution.
