After merging WT-6840, we saw some fallout on Evergreen where PPC machines weren't able to build the fuzz targets properly. I've temporarily disabled building the targets on PPC.
If we begin using the fuzzer in Evergreen and feel that we're getting value out of it, we should try to get it working on PPC since testing across a range of environments is always a good thing.
The Evergreen failure we can can be found here: https://evergreen.mongodb.com/task/wiredtiger_ubuntu1804_ppc_format_stress_sanitizer_ppc_test_fdf8783a2dccc30517248cd0130a0aab4fe5b632_21_02_03_12_38_40
And the compilation error looked like this:
