### Description Several tests in !9133 fail due to `gmake`. For example: ``` gmake: *** [Makefile:7: T15261a] Error 1 ``` we've disabled these tests, but this is the tracking ticket for the fix. ### Impacted Tests Check these off as you re-enable them: * [ ] T15261a: requires support for `-with-rtsopts="-t -s"` and `+RTS --info` * [ ] T15261b: requires support for `+RTS --info` * [x] T16318: !10150 * [ ] T17648: JS backend doesn't compute exact CafInfos (HasNoCafRefs) * [x] T20214: !10150 * [ ] T21336c: bad handling of setFinalizerExceptionHandler * [ ] rtsopts002: requires support for `-with-rtsopts="--info"`, `-with-rtsopts="-C0"`, and GHCRTS environment variable * [ ] withRtsOpts: requires support for `-with-rtsopts="--info"` and `-with-rtsopts="-t"`
