Well, this is because the target set in default-gecko-config is i686-android-linux, and that is not a valid triplet for android-based systems. You were lucky that it worked until now because our checks in were broken.

IOW, this should be fixed in gonk-misc.

Target triplets have the form cpu-manufacturer-kernel, where the kernel part can be kernel-os.

On desktop linux, a typical triplet is i686-pc-linux or i686-pc-linux-gnu. cpu=i686, manufacturer=pc, kernel=linux, os=gnu.

On android, a typical triplet is arm-none-linux-android. cpu=arm, manufacturer=none (doesn't matter), kernel=linux, os=android

or arm-none-linux-androideabi (os=androideabi)

In your case, it's: i686-android-linux. cpu=i686, manufacturer=android, kernel=linux.

The manufacturer is simply ignored by most things. And if you look at toolchains, they have gcc prefixed with $cpu-$kernel-$os. Thus your toolchain prefix being .../x86_64-linux-android-

A proper triplet in your case would be i686-none-linux-android. i686-linux-android would actually work because we're actually lax. But i686-android-linux doesn't work anymore.

Also note how "checking target system type..." in your log says "i686-android-linux-gnu" instead of "i686-android-linux". That's because your input (i686-android-linux) goes through config.sub, which canonicalizes the form for the kernel-os part to be complete: linux-gnu instead of linux. Which indicates a linux+glibc system, which is definitely not android. Note the syntax and config.sub come from autoconf. I'm not making things up.

Hi Michael,

Would you help to review this? I've tested on nexusplayer-l.
