build fails for evbarmv7hf-eb

Hi,

Build fails for evbearmv7hf-eb:

  % ./build.sh -U -m evbearmv7hf-eb tools release
  ....
  --- cleandir-sys ---
nbmake[7]: "/var/build/src/sys/modules/dtrace/lockstat/Makefile" line 22: warning: String comparison operator should be either == or !=
nbmake[7]: "/var/build/src/sys/modules/dtrace/lockstat/Makefile" line 22: Malformed conditional (${ARMV} > 4)
  ....

For earm, variable ARMV is defined as follows.

  ARMV:= ${MACHINE_ARCH:S/earmv//}

As a result, we obtain "7hfeb" in the case of evbearmv7hf-eb.
Before comparing it with 4, we must also remove "eb" and "hf".
Please apply the attached patch.

Thanks,
Rin
