scripts: always create lib32 and lib64 symlinks
Unconditionally create the lib32 -> lib/ and lib64 -> lib/ symlinks.
This is reportedly a fix to build a toolchain for a 32-bit target on
a 'pure' 64-bit host (eg. on Fedora FC12, host libs are in lib64/,
and there is no lib -> lib64 symlink, as we can see on other distors,
as Debian). As gcc only puts static host lib in lib64/ (along with
target files in subdirs), we can safely create the symlinks.
Also note that the symlinks are summarily removed at the end
of the build.

7 Please note the warning under @option{-fgcse} about
8 invoking @option{-O2} on programs that use computed gotos.
10 +NOTE: In Gentoo, @option{-D_FORTIFY_SOURCE=2} is set by default, and is
11 +activated when @option{-O} is set to 2 or higher. This enables additional
12 +compile-time and run-time checks for several libc functions. To disable,
13 +specify either @option{-U_FORTIFY_SOURCE} or @option{-D_FORTIFY_SOURCE=0}.
17 Optimize yet more. @option{-O3} turns on all optimizations specified
