Enable i18n support on Linux

[mtbrandy]

The upstream changes from 3.20.17 to 3.22.24 turned on i18n support by default. This is causing test case crashes (~150) on Linux.

Disabling via the i18nsupport=off works around the problem, but this needs further investigation.

Interestingly, this seems to work out of the box on the simulated (intel) and ppc64LE environments.

According to http://src.chromium.org/chrome/trunk/deps/third_party/icu46/README.chromium
pre-built data libraries have been checked in. The ICU User Guide http://userguide.icu-project.org/icudata#TOC-Sharing-ICU-Data-Between-Platforms says these are byte-ordered -- The ones that are checked in are little endian.

Hello, I was working on adding i18n support for big endian, being part of the MIPS v8 team. Chromium ICU now supports big endian MIPS targets, adding PPC as well should be very simple (should just add few conditions to icu.gyp file). You have more details here:
v8mips/v8mips#197

Thank you, I will add the PPC changes and enable i18n.
