Your config.log has a lot of errors like

/usr/include/hfs/hfs_format.h:794:2: error: unknown type name
'uuid_string_t'; did you mean 'io_string_t'?

when checking for Apple frameworks like AudioToolbox, AVFoundation,
VideoToolbox and more, so configure is evidently not enabling them.

What these errors mean or if they are consequence of a configure change
or some system/environment update in your Mac, i can't say.
