[Xen-devel] [PATCH 5/5] travis: pass a correct CC/CXX if CROSS_COMPILE is defined

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

After b41666f2c1 Xen no longer overwrites the names of the build
toolchain utilities required during the build process, and instead
uses the values from the environment.

In that case, if the user wants to define CC or other variables to
point to specific toolchain utilities to use it must also take into
account that such variables must be prefixed with CROSS_COMPILE, since
Xen will no longer do this.

Fixes: b41666f2c1 ('config: don't hardcode toolchain binaries')
