How to handle shell expansions in GNU Make under Ubuntu?

Given this very simple Makefile:

all:
    @mkdir -pv test/{a,b}

I get this output on OS X 10.6.8 and CentOS 5.5:

mkdir: created directory `test'
mkdir: created directory `test/a'
mkdir: created directory `test/b'

But on Ubuntu 11.04 I get this:

mkdir: created directory `test'
mkdir: created directory `test/{a,b}'

Running the command mkdir -pv test/{a,b} manually in the shell on all platforms gives the expected result.

The version of GNU Make is the same on all platforms:

GNU Make 3.81

What's different under Ubuntu and why doesn't the shell expansion work there?

Make has a way to do this with its own functions:

    @mkdir -pv $(addprefix test/,a b)

gets expanded to

    @mkdir -pv test/a test/b
