On Solaris, sed throws away the NUL bytes from the stream, even in C locale. So instead of postprocessing bison's stderr to neutralize changes in value of `argv[0]`, use an envvar to actually neutralize variations of `argv[0]` during tests. Reported by Dagobert Michelsen. <https://lists.gnu.org/r/bug-bison/2021-08/msg00025.html> * src/main.c (main): Change `argv[0]` if BISON_PROGRAM_NAME is defined. * tests/bison.in: No longer mess with stderr, just pass the expected BISON_PROGRAM_NAME value.
