FreeBSD make has the ability to uppercase or lowercase a variable
by using the U or L modifiers. Say, if FOO=bar, then ${FOO:U} == BAR.

NetBSD make does not have this ability. Since NetBSD make uses U and
L for something totally different, we would need a different set
of modifiers. I propose something like modifiers of "tu" and "tl"
(for "toupper" and "tolower").

If I kick in the code would someone commit it? Please?
