libstdc++ already uses -f{function,data}-sections, and at one point passed
--gc-sections when linking.  However, the linker's gc caused problems:

    http://gcc.gnu.org/ml/gcc/2001-03/msg00401.html

and it's now disabled by default.  The bits to enable it for GNU ld are
still in the configury, however, can can be easily tweaked to turn it on
and try it.

If the binutils folk have made fixes to --gc-sections since then, it might
be worth trying.
