coreutils env does not export variable

[sachintu47]

When running test script "mantest" for jqport as below.

"env PAGER=less $VALGRIND $Q $JQ -L "$mods" --run-tests $JQBASEDIR/tests/man.test".

PAGER variable was not part of the executable environment.

Following solution worked.

1. Removing env variable as in below.
   "PAGER=less $VALGRIND $Q $JQ -L "$mods" --run-tests $JQBASEDIR/tests/man.test".

2. Using native env binary.
   "/bin/env PAGER=less $VALGRIND $Q $JQ -L "$mods" --run-tests $JQBASEDIR/tests/man.test""
