[Buildroot] [PATCH 1/2 for 2015.11.x] support/check-host-rpath: remove trailing '/' in host dir

[Yann E. MORIN <yann.morin.1998@free.fr>]

Despite the comment saying so, the trailing '/' in the host directory is
not removed. note however that it is properly removed from extracted
RPATH tags.

This is not visible when the host directory is our default $(O)/host
location, but breaks for user-supplied external host ditrectory, when
the user leaves a trailing slash in the path.

Fix that.

Sorry for the mess, it's a case I did not test...
