[RFC,1/1] testcase fail while using cross-test-ssh wrapper

  I did a regression test yesterday, and found tst-locale-locpath.sh and
tst-rtld-preload.sh failed due to some script problem. The ssh wrapper
is invoked twice on these testcase, seems some of the arguments are
not pass correctly for cross test.

tst-locale-locpath.sh test cmd:

Sorry, this patch doesn't look correct to me.  Why is it appropriate to
ignore evironment variables passed to the test script?

Thanks,
