[Buildroot] [PATCH 1/2] Avoid misleading error output caused by missing shell quotes

[Jens Stimpfle <debian@jstimpfle.de>]

Notes:
    When g++ is not installed, a misleading error message turns up because
    of a bad combination of an unquoted shell variable and control flow.
    
    > ~/buildroot$ make
    >
    > You may have to install 'g++' on your build machine
    > /home/testuser/buildroot/support/dependencies/dependencies.sh: 136: [: -lt: unexpected operator
    
    This is a nonintrusive workaround.
