The value returned on AIX for platform.machine() is not the best value to map the architecture from. Use platform.system to determine if we are on AIX and if so set host_arch to ppc64 as AIX 6.1 (the earliest supported) only provides a 64 bit kernel AIX was reporting warning that offset may be used uninitialized modified: build/detect_v8_host_arch.py modified: build/standalone.gypi modified: src/hydrogen-bce.cc R=mbrandy@us.ibm.com, jkummerow@chromium.org BUG= Review URL: https://codereview.chromium.org/1006583004 Cr-Commit-Position: refs/heads/master@{#27463}
