11:50 PM Revision 1a207650 (git): DRY up CARGO_VERBOSE for JITs
-
- This gives a better signal when say you try to run `make zjit-test` on a
YJIT-only build. -
- Fixes `TestZJIT::test_require_rubygems`. It was crashing locally due to
false collection of a live object. See
<https://alanwu.space/post/write-barrier/>.
