No, the tests/*.TXT files don't change. "make check" passes,
"ICONV_EBCDIC_ZOS_UNIX=1 make check" passes as well.

That's because
  - The iconv _library functions_ don't test the environment variable.
    It's the iconv _program_ which tests it and passes the information
    to the library.
  - The unit tests make use of a program 'table-from' that invokes the
    library, not the iconv program, and therefore works the same way
    regardless of the setting of the environment variable.
