[Pkg-chromium-maint] [PATCH] Add LINK.host to BUILD_ARGS to prevent build failures

[Andrew Chant]

The default Makefile produced by gyp defines "LINK.host ?= g++".
This causes runtime errors during the build if g++ isn't identical
to the CXX and CC versions used.

This patch updates debian/rules to define LINK.host wherever CXX.host
and CC.host are defined.

Tested:
 Built chromium-20.0.1132.17~r138701 with gcc-4.6 but with g++
 pointing to g++-4.7.  Prior to fix, build would crash with
 "Floating point exception" whenever protoc was run.
