Subject: [PATCH 0/2] nolibc: fix two build issues at -O0

Hello Paul,

please find in this series two build fixes to apply on top of the series
you've already queued:
 - gcc errors at -O0 because it doesn't eliminate non-inline code and
   keeps the reference to the external "environ" from getenv()
 - clang fails at -O0 because __builtin_strlen() calls strlen()

I don't care about optimizing at -O0 by definition but at least it should
build and work correctly! I've verified that rcutorture still runs.

Thanks!
Willy
