Make LEC_CHECK 0 default for non-ORFS test-suite

[oharboe]

Description

designs using ORFS, but not part of ORFS test-suite, probably don't want to run LEC_CHECK=1.

The trick is that LEC_CHECK=1 is a reasonable default for the ORFS test scripts themselves.

Suggested Solution

Make LEC_CHECK=0 by default, pass in make LEC_CHECK=1 in CI.

Some designs explicitly disable LEC_CHECK in config.mk and they override make LEC_CHECK=1.
