[tools-linking] _environ/environ are NODIRECT but getenv/putenv/setenviron are not

[ольга крыжановская]

Roger,
do you remember the use case which required to add NODIRECT to environ
and _environ in
http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/lib/libc/sparc/mapfile-vers?
I am trying to understand why environ was marked as NODIRECT but
getenv/putenv/setenviron were not.
