One more build break - "port evbearm-eb"

[Paul Goyette <paul%whooppee.com@localhost>]

src/build.sh indicates that "evbearm-eb" should be a valid "alias"

        MACHINE=evbarm          MACHINE_ARCH=earmeb     ALIAS=evbearm-eb

However, if one tries to do a

        ./build/sh -m evbearm-eb release

the build fails with (manually wrapped)

        --- obj-libgcc ---
        nbmake: "/build/netbsd-local/src/share/mk/bsd.files.mk" line 110:
        Wrong number of words (1) in .for substitution list with 2 vars
        *** [obj-libgcc] Error code 1
