Not much in current code base, it's only used by:
tests/tcg/Makefile:ifneq ($(call find-in-path, $(CC_I386)),)

So if you set CC_I386 to an absolute PATH, it's not going to run the I386_TESTS.

This is not very important yet, but better for correctness.

In the future, I hope qemu can have a better tcg-test framework (I am doing some experiment in https://github.com/elmarco/qemu/tree/tcg-tests/tests/tcg), and as part of this work, I found this bug.
