Subject: Clean up *.la after installing compiler/libraries.

Having *.la in the installation directory breaks ltrace: in ltrace,
libtool somehow considers libsupc++ to be an "accessory library" and
does not add -lsupc++ to the link flags. Neither Ubuntu, nor RedHat
include *.la files into their packages for libstdc++.
