[chirp_users] New Daily Build

[Build System]

Greetings,

A new daily build of CHIRP is available.  This includes changes made
directly to the tree yesterday, and may include additional features,
bug fixes, and/or bugs.  If you are interested in trying it, grab it
from the following location:

  http://trac.chirp.danplanet.com/chirp_daily/daily-20210922


A list of the changes included in this build (since the last daily)
follows:

Changes for Build #663
[Dan Smith <3046399+kk7ds at users.noreply.github.com>] Merge pull request #5 from mfncooper/fix_8845

Don't die if GTK Mac integration is missing

[Martin Cooper <mfncooper at gmail.com>] Don't die if GTK Mac integration is missing

If GTK Mac integration is missing, Chirp dies when it tries to log this
fact. The code is designed to handle the absence of this capability and
simply omit the Mac-specific features, so handle the logging gracefully
and carry on.

Fixes #8845
