Subject: [PATCH] configure: Fix linux-user host detection for riscv64

Mirror the host_arch variable from meson.build, so that we
probe for the correct linux-user/include/host/ directory.

Fixes: e3e477c3bca0 ("configure: Fix cross-building for RISCV host")
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
