scripts/addToolsVersion: handle elf2flt

The one was missing from the list.

It is very improbable that we ever need it, as elf2flt does no release,
and we always get it from CVS head. But for the sake of consistency, we
just add it.

     2  The generated libtool for building libstdc++ adds the -nostdlib option to the

     3  g++ command for linking but doesn't add -lgcc.  This causes a "hidden symbol"

     4  error when linking against the libstdc++ shared object.  This patch adds gcc

     5  to the list of libraries linked against when linking libstdc++.
