* template/ruby-runner.c.in: wrapper to set dynamic loading path environment variable. /bin/sh on Mac OS X 10.11 (El Capitan) clears DYLD_LIBRARY_PATH. it must: - do nothing even if current directory is not present - do not set other environment variables, e.g. PWD, SHLVL, etc - do not open other FDs, e.g. pipes for timer thread git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@52008 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
