Maybe:

  $ git grep -h -B5 -A1 pcre_jit Makefile
  # When using USE_LIBPCRE1, define NO_LIBPCRE1_JIT if the PCRE v1
  # library is compiled without --enable-jit. We will auto-detect
  # whether the version of the PCRE v1 library in use has JIT support at
  # all, but we unfortunately can't auto-detect whether JIT support
  # hasn't been compiled in in an otherwise JIT-supporting version. If
  # you have link-time errors about a missing `pcre_jit_exec` define
  # this, or recompile PCRE v1 with --enable-jit.

It looks like autoconf turns on USE_LIBPCRE1, but isn't smart enough to
test NO_LIBPCRE1_JIT.
