toolchain-external: do not allow the user to select hard/soft float

Commit ba92d6ef68eeb37ba435648fcfbd1dbe13212e6d made hard float the
default when Cortex-A8 and Cortex-A9. The problem it was trying to fix
is that the newer Linaro toolchains (2012.05 and 2012.06) are
hard-float, so the default selection of soft-float enabled on ARM
doesn't work for those toolchains.

Unfortunately, not selecting soft-float causes problems with
the Crosstool-NG backend at the moment.

As an intermediate solution, make the soft float option disappear when
using external toolchain: the toolchain will decide by itself whether
to generate hard float or soft float code.

sudo: fix main executable permissions

The sudo executable is installed without the setuid bit set, which prevents
sudo from working.

This patch adds a post-install hook to fix the permissions of the sudo
executable.
