From 6ed8bc71997e0dc6877bccc1e2ce75a73b6d8b56 Mon Sep 17 00:00:00 2001 From: Andrew Hsieh Date: Wed, 17 Jul 2013 17:35:46 -0700 Subject: New x86 toolchain: x86_64-linux-android-4.7 (darwin-x86) This toolchain can generates x86, x32, and x86_64 (default) code. Android build system already adds "-m32" to HOST_GLOBAL_CFLAGS and HOST_GLOBAL_LDFLAGS for projects to compiled in x86.
