gle-graphics: universal variant doesn't work

[ryandesign (Ryan Carsten Schmidt)]

Trying to install gle-graphics with the +universal variant results in this error:

Just to re-confirm, the issue remains with gle-graphics @4.2.5.

To work around the build failure, I disabled the universal variant in r100860. This bug should be reported to the developers of gle-graphics, and the universal variant should be re-enabled once the developers have fixed it.

See #51225.

This may be fixed once gle-graphics is updated to 4.3.x which now builds using CMake instead of autotools. I'm working with upstream to resolve a variety of problems before we can update to that series.
