Subject: [PATCH] toolchain_util: fix parsing emerge --pretend output

Fix parsing the following output:

    [ebuild  N    ] dev-libs/gmp-5.1.3-r1 to /usr/x86_64-cros-linux-gnu/
    [ebuild     UD] sys-libs/timezone-data-2013d [2014i-r1] to /usr/x86_64-cros-linux-gnu/

The previous regex did not account for upgrades and got confused by the
`[2014i-r1]` listing and goobbled up too much of the string. I am not
sure *why* portage is reporting an upgrade when --emptytree is also used
but there it is. Match all not-] characters instead.
