Subject: Make NaCl run in Chrome on the Mac.

Note: this is a *slight* rework of CL 555082, which accidentally broke the
build.  That CL was reviewed and LGTM'd byt sehr@ and bsy@.

BUG=none
TEST=none

Review URL: http://codereview.chromium.org/551172

git-svn-id: svn://svn.chromium.org/chrome/trunk/src@37279 0039d316-1c4b-4281-b951-d872f2087c98
