[ovs-dev] [PATCH v2] configure: Fix check for rte_config.h to handle cross-compilation.

The check for rte_config.h in acinclude.m4 used AC_CHECK_FILE, but this
macro is intended to check for a file on the host system, not the build
system, which means that it fails unconditionally in a cross-compilation
environment. However, the intended check here is for a header file,
which is part of the build system. To check for part of the build system,
we can just use "test", so this commit makes that change.
