Subject: [PATCH 2/2] Use earliest supported macOS version in configure by
 default

Use the first value of DEPLOYMENT_TARGET_SUGGESTED_VALUES plist key
instead of MACOSX_DEPLOYMENT_TARGET.

Also drop support for using "buildSettings" key, this is something very
old and certainly not used by any of the still supported Xcode versions.

And simplify the commands used in a configure, in particular use a
single sed command with "p" modifier instead of using grep and then sed.
