v8: prevent unnecessary rebuilds

Android.mksnapshot.mk is parsed twice when building for a 64-bit device,
for example once for arm64 and again for arm.  Using += for
LOCAL_CFLAGS_v8_target_* results in cflags being added twice for the
32-bit version.  For a 32-bit device the file is only parsed once and
the cflags are not duplicated.

The cflags are used for host modules, which are shared between builds of
different products.  If the cflags change between products the command
line will change and ninja will rebuild all the files.

Replace += with := for the first assignment to LOCAL_CFLAGS_v8_target_*.

Getting the Code

Checkout depot tools, and run

fetch v8

This will checkout V8 into the directory v8 and fetch all of its dependencies. To stay up to date, run

git pull origin gclient sync

For fetching all branches, add the following into your remote configuration in .git/config:

    fetch = +refs/branch-heads/*:refs/remotes/branch-heads/*
    fetch = +refs/tags/*:refs/tags/*
