gstreamer1-gst-plugins-base @1.24.1_1 - Fatal error: 'stdatomic.h' file not found

[RobK88]

gstreamer1-gst-plugins-base @1.24.1_1 fails to build on lion and mountain lion with the following error message -- fatal error: 'stdatomic.h' file not found.

See the attached main.log.

The workaround is to build with a compiler that has atomic support such as clang-11. (Thanks @kencu)
