mkcheck breakage (and repairage)

            * mkcheck.in: workaround for bash 2.01 IFS bug.

makes mkcheck work correctly *only* for 2.01 now.  Before the change,
CXXFLAGS was set to "-ggdb3 -DDEBUG_ASSERT" and INCLUDES was set
to "-I/home/pme/src/unified/libstdc++-v3/testsuite" but now it's
CXXFLAGS="-ggdb3" and INCLUDES="-DDEBUG_ASSERT".  This causes every test
to fail to compile, since the -Ipath is lost and debug_assert.h can no
longer be found.

I am committing the following patch.  Please test that it works for
bash 2.01.  (Since mkcheck is a temporary stopgap measure, I'm not as
concerned about bug-for-bug compatability with older bash'es as we would
be if mkcheck were a permanent thing...)
