Steps to reproduce the problem:
1. Download http://gsdview.appspot.com/chromium-browser-official/chromium-51.0.2704.63-lite.tar.xz

2. Try to build it with these flags:

$ cat include.gypi 
{
  'variables': {
    'target_arch': 'x64',
  }
}

$ cat oe-defaults.gypi 
{
  'variables': {
    'use_system_harfbuzz': 1,
    'use_system_fontconfig':1,
    'use_system_libjpeg':1,

    'use_kerberos': 0,
    'use_cups': 1,
    'use_gnome_keyring': 0,
    'linux_link_gnome_keyring': 0,
    'use_gconf': 0,
    'use_gio': 0,
  }, 
}

3. Start build.

What is the expected behavior?
I don't know.

What went wrong?

Did this work before? N/A 

Chrome version: 51.0.2704.63  Channel: n/a
OS Version: 
Flash Version: 

I am running this through a Bitbake recipe for Yocto to build chromium-lite but it shouldn't be a problem. The big brother, Chromium from the same version builds fine, except that that last few flags are not needed for it, because it contains the ICU and the vtunejit 3rd party codes built-in. These flags are omitted for Chromium:

-Dwant_separate_host_toolset=0 -Duse_system_icu=1 -Dicu_use_data_file_flag=0 -Dv8_enable_vtunejit=0 -Dtest_isolation_mode="noop" '

What else would be needed or what should be changed to make chromium-lite tree build?
