Did this used to work?  I'd be surprised if did; if so it was probably a
bug in the old version of make.

You need to be sure that make knows where the variable ends, so that
requires quoting the end paren at least from make, AND you need to quote
the parens to the shell as well.

Does it work if you just switch to the alternative delimiters:

  all: $${shell find . \( name "*.swp" \)}

?

What about if you put the command in a variable?

  find := find . \( name "*.swp" \)
  all: $$(shell $$(find))
