Subject: env.sh: Use a more portable way of counting online processors

getconf _NPROCESSORS_ONLN should be available on Linux, FreeBSD
and OSX at least:

http://linux.die.net/man/1/getconf
https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/getconf.1.html

getconf NPROCESSORS_ONLN is BSD variant which Haiku provides.

One might want to handle Solaris too some day...
