Hi all,

This has been merged. But I now wonder, if this would be better with LTP_
prefix, e.g. LTP_ENABLE_DEBUG, because it's a variable which is defined by LTP
user. WDYT?

This might be also case for TST_NO_CLEANUP, but it's rarely used, thus my
concern is more about LTP_ENABLE_DEBUG.

Kind regards,
Petr
