    valgrind: Fix build on ARMv7
    
    The valgrind configure script checks if host_cpu is set to armv7 or arm.
    By default --host is set to arm-openwrt-linux and the host_cpu variable
    is set to arm. Then the valgrind build tries to compile valgrind for
    armv6 and fails. Set it explicitly to armv7 to compile valgrind with
    armv7 support.
