This also works for me (x86_64-apple-darwin10.4):

[macbook] build_w/gcc% make -k check-g++
RUNTESTFLAGS='--target_board=unix"{-m32,-m64}"'
...
        === g++ tests ===

Schedule of variations:
    unix/-m32
    unix/-m64

Running target unix/-m32
Using /sw64/share/dejagnu/baseboards/unix.exp as board description file for
target.
Using /sw64/share/dejagnu/config/unix.exp as generic interface file for target.
Using /opt/gcc/work/gcc/testsuite/config/default.exp as
tool-and-target-specific interface file.
