If it's a matter of the tests actually depending on regex library
calls, I would say
that's something that would probably need to be fixed in the test, since not all
C libraries are going to have the same implementation. But if the tests are
depending on the behavior of the "grep" command, the fix might be as simple
as ensuring that the test environment has GNU grep installed in the path ahead
of busybox grep. (since GUN grep uses PCRE rather than MUSL for its regex.)
