[bug #65596] Test for let function not available in .FEATURES

[Jouke Witteveen]

Follow-up Comment #1, bug #65596 (group make):

You're right. I guess it's too late to fix that now, since it will not be
fixed in all releases that have the "let" function.

You can test for its presence with the following construct:

$(filter builtin,$(foreach let,unavailable,$(call let,,,builtin)))

This will expand to "builtin" if there is a built-in "let" function and to the
empty string otherwise. Without the outermost "filter", it would expand to
"unavailable" when there is no built-in "let" function.
