Seems ncurses 5.7 need build host stage for tic step; if use host tic
(ubuntu) the build process hang in the below step.
So I guess need to build ncurses host stage to build new tic

and provided a patch to that efect.

And in fact, we do need "tic" to run on the _build_ system to properly
generate the terminfo database.

Note: this is fully functional, but still requires a litle bit of
tweaking so that ${CT_BUILD}-gcc gets used instead of plain gcc.
But that's a minor problem for now...

     1 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-4.1-alpha-mieee-default.patch

     2 Set the default behavior on alpha to use -mieee since the large majority of

     3 time we want this (bad/weird things can happen with packages built without

     4 -mieee).

     5 

     6 To satisfy those people who may not want -mieee forced on them all the time,

     7 we also provide -mno-ieee.
