Re: findutils 4.8.0 fails to build on macOS 10.14, 10.15, 11.1

The build failure I reported in

    https://lists.gnu.org/archive/html/bug-findutils/2021-01/msg00050.html

was because the build was trying to use glibc's regex library. This
doesn't work on macOS. I avoided that by passing
`--without-included-regex` to `configure`. This fixed the identical
build failure with wget.

However, this reveals a different error:

    Undefined symbols for architecture x86_64:
      "_re_compile_pattern", referenced from:
          _insert_regex in libfindtools.a(parser.o)
      "_re_match", referenced from:
          _pred_regex in libfindtools.a(pred.o)
      "_re_set_syntax", referenced from:
          _insert_regex in libfindtools.a(parser.o)
    ld: symbol(s) not found for architecture x86_64

Build logs are available at

    https://github.com/Homebrew/homebrew-core/actions/runs/514827463

The error starts at

    https://github.com/Homebrew/homebrew-core/pull/69761/checks?check_run_id=1776152857#step:7:1081

Assistance would be appreciated.
