Nit: let's keep <test>/<subtest> convention here as well?
Failure doesn't always set errno, this will be quite confusing
sometimes. Especially for higher-level libbpf APIs, which don't set
errno at all.
If test wants to log additional information, let it do it explicitly.
Also, _CHECK already logs error message, so this is going to be
double-verbose for typical case. I'd say let's drop these error
messages and instead slightly extend _CHECK one with line number (it
already logs func name).

So I'm neutral on this rename, I even considered it myself initially.
But keep in mind, that succ/fail in env means number of tests, while
test->succ/fail means number of assertions. We don't report total
number of failed checks anymore, so it doesn't matter, but if we ever
want to keep track of that at env level, it will be very confusing and
inconvenient.

Did you move it here just to access env.test->succ_cnt in _CHECK()?
Maybe add test__success() counterpart to test__fail() instead?

Given my comment above about too verbose logging, I'd say let's keep
this simple and have just
extern void test__fail()
And let _CHECK log file:line.
