internals: fix stripping host binaries

The gcc used by linaro has a version number specific to Linaro, but
identifies itself with its upstream version numbering scheme.

This breaks the strip in the finish step, because the actual gcc version
is not the same as the configured one (eg. 4.5.2 vs. linaro-4.5-2011.02-0).
