(Previously mentioned on pkgsrc-wip-discuss where this message is also
bcc'd.)

Is this fix okay?

By the way, make(1) says: "Variables in make are much like variables in
the shell, and, by tradition, consist of all upper-case letters."

But that "all upper-case letters" means that X11BASE, MOTIF12BASE,
EMACS_USE_XAW3D, P4ROOT, MPG123_ARM_FIXED64, and various other variables
are illegal. So make(1) appears to be wrong.

And we know and sh(1) says "Variables set by the user must have a name
consisting solely of alphabetics, numerics, and underscores - the first of
which must not be numeric."

My patch above has it start with uppercase letter and then followed by
optional letter, number, dash and/or underscore. (I don't care if it ends
with a dash or underscore, but maybe it should check for that too?)
