fcron @3.2.1: Undefined symbols: _strndup

[ryandesign (Ryan Carsten Schmidt)]

fcron fails to build on Snow Leopard because it uses strndup. Using the legacy support port group might help.

fcron: add legacy support to attempt to fix builds

fixes #59099

[ryandesign (Ryan Carsten Schmidt)]

​This does not appear to be enough. It looks like it's not using our LDFLAGS.

fcron: adjust Makefile to actually use LDFLAGS instead of just LIBS

I'm not entirely sure how this every worked; only legacy build were
failing. Force re-building to see if this breaks anything.
Tested locally on 10.13.6 and 10.15.1

See #59099

I'm waiting on the > 10.9 builds to start - everything else seems to work

Replying to Kurt Hindenburg <kurt.hindenburg@…>:

I'm not entirely sure how this every worked

It was getting the library path from LIBRARY_PATH. (Only very old versions of clang don't support that.) As for the rest of our LDFLAGS, it wasn't using them, so it wasn't built with headerpad_max_install_names and it wasn't built for the right architectures. With your change, now it should be.

builds look good
