The following two scripts allow for the update and roll of the mac
toolchain (Xcode) via DEPS instead of thru an infrastructure install
script. The upload / download nature of the script follows somewhat
what Windows does with visual studio files and what Mac already does
for clang rolls.
build/package_mac_toolchain.py takes an Xcode.app directory
and packages up what the parts the Mac build uses into a tar file
and uploads it to gs://chrome-mac-sdk/
build/mac_toolchain.py runs as part of hooks, downloads
and decompresses the mac toolchain, and points system files to this
new directory with the DEVELOPER_DIR environment variable.
Setting DEVELOPER_DIR throughout gyp-ninja requires this GYP CL:
