Patch to unset all mentioned environment variables

When trying to install dev-qt/qtcore-5.9.2 the configure fails phase:

>>> Configuring source in /tmp/portage/portage/dev-qt/qtcore-5.9.2/work/qtbase-opensource-src-5.9.2 ...

Please make sure to unset the QMAKESPEC, XQMAKESPEC, QMAKEPATH,
and QMAKEFEATURES environment variables prior to building Qt.
 * ERROR: dev-qt/qtcore-5.9.2::gentoo failed (configure phase):
 *   configure failed

The attached patch to the ebuild enables compiling in presence of the variables.

From configure:
if [ -n "$QMAKESPEC" ] || [ -n "$XQMAKESPEC" ] || \
        [ -n "$QMAKEPATH" ] || [ -n "$QMAKEFEATURES" ]; then
    echo >&2 "Please make sure to unset the QMAKESPEC, XQMAKESPEC, QMAKEPATH,"
    echo >&2 "and QMAKEFEATURES environment variables prior to building Qt."
    exit 1
fi

Since configure is called called by all qtbase packages, I think we should unset in the eclass instead. Please review attached patch.
