Smoke failure (utf8 downgrade in ENV)

On David's request I looked deeper in the smoke logs, and I saw this
on HP-UX 11.00. What to do about that?

perl-current/t 108 > ./perl TEST -v ../t/op/magic.t
t/../t/op/magic ... 1..179

ok 8 - *2 appears to be defined at the outset

not ok 162 - ENV store downgrades utf8 in setenv

### Since not all tests were successful, you may want to run some of

### See the INSTALL document's section on "make test".
### You may have to set your dynamic library search path,
### LD_LIBRARY_PATH, to point to the build directory:
###   setenv LD_LIBRARY_PATH `pwd`; cd t; ./perl harness
###   LD_LIBRARY_PATH=`pwd`; export LD_LIBRARY_PATH; cd t; ./perl harness
###   export LD_LIBRARY_PATH=`pwd`; cd t; ./perl harness
### for csh-style shells, like tcsh; or for traditional/modern
### Bourne-style shells, like bash, ksh, and zsh, respectively.
