Making GCC 4.3 the default on alpha

[Arthur Loiret <aloiret@debian.org>]

Hi!

Since Debian version 4.3.3-2, gcc-4.3 has a fix for PR
middle-end/38969 [0], which, added to some more fixes committed to the
gcc-4_3-branch or backported from trunk, made it suitable enough to
build glibc on alpha. We are now planning to make it the default
version on alpha, do you have any objection about this?

Thanks,
