The above line looks weird. Could you explain what the intention was?

[bbudge, 2012/08/14 16:53:42]

'nacl_untrusted_build' indicates that we are building for the Native Client
sandbox, which is a restricted POSIX environment. We need to exclude any
platform specific files, as they won't build. We need this extra bit because
NaCl untrusted builds can be done on many different platforms. While Android
isn't one of them, this pattern works and is consistent with the others. And in
the future, who knows?
