Test case for yecc, switching between test mode and normal mode
Test case for yecc, switching between test mode and normal mode

With a yecc grammar in the project, and this sequence of commands:

$ make clean
$ make check
$ make
$ make

the "make check" succeeds. The first "make" fails because the .erl
file built from the .yrl file doesn't exist. The second "make"
succeeds.

Add a test case for this situation.
