>Description:
From make(1)

     :Mpattern
          Select only those words that match pattern.  The standard shell
          wildcard characters (`*', `?', and `[]') may be used.  The wildcard
          characters may be escaped with a backslash (`\').

Actually dash inside [] works partially.

    0 cheusov>cat ~/tmp/1.mk
    foo = -

    all:
        @echo match=${foo:M[.-]}
        @echo match=${foo:M[-.]}
    0 cheusov>make -f ~/tmp/1.mk
    match=
    match=-
    0 cheusov>

That is, dash in the end of [] doesn't work as it works in shell.

    0 cheusov>touch -- -
    0 cheusov>echo [-.]
    -
    0 cheusov>echo [.-]
    -
    0 cheusov>
