test binary

In zLinux for o/s390 (SuSe v 8 64 bit) is a binary 'test' that we use to
test for the existence of files.  One of our tests uses a wildcard to check
for any *.hdr files in a certain directory.  When there is more than one
*.hdr file in this directory, the test fails with an exit 2, so we are not
processing any files.  Is there an option that will allow the test command
to end with exit 0 if multiple files are found?  Or is this a bug?

We are using the test command on aix v 5.2 to process multiple files with
no problems.

Example of failure:

maestro@lnxrzp1:~/tmp> ls -al
