Subject: Properly detect x32.
X-Git-Tag: archive/raspbian/2%0.164.3108+git31e19f9-1+rpi1^2~1
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=6741078b26d2824f710feabacb508ddef604938d;p=x264.git

Properly detect x32.

As usually, x32 gets mistaken for amd64 (both are x86-64 ABIs after all).
This version doesn't use any assembly yet, a proper port is needed.

Gbp-Pq: Name properly_detect_x32.patch
