u-boot requires openssl includes and libs on host, add the missing
dependencies and set HOSTCFLAGS so the build can pick up openssl from
the LE toolchain.
Also fix HOSTLDFLAGS to use HOST_LDFLAGS which adds an rpath to
toolchain/lib so the dynamic linker uses our openssl libs, not those
from the host.
