Steps to reproduce:
I tried to build Fennec for an x86 Android tablet.
It failed to build APKOpen.cpp due to a chain of header dependencies ending in xpcom-config.h. Since xpcom hadn't been built yet, it couldn't find the header.
It should have known there was an stl dependency and built correctly. The fix is to add STL_FLAGS= to mozglue/android/Makefile.in.

You should ask review on someone. Brad, could you perhaps review this patch?
Thomas, why does clearing the STL_FLAGS fix this bug? And why x86 only?

> Thomas, why does clearing the STL_FLAGS fix this bug? And why x86 only?
When i pulled the latest code some time after the mozglue portion was reorganized from other-liscenses, it built fine for ARM/Android, but not for x86/Android. The new code created a dependency on stl_wrappers for APKOpen. Specifically the cstring file. The cstring file has a dependency on xpcom and it hadn't been built yet when APKOpen was being built. The stl_wrappers dependency doesn't appear to be present in the ARM build. So I made it for x86 only so as to not affect the ARM build.
As far as to why/how the solution works, I got the recommendation from Mike Hommey and don't know what further implications it has.
You can probably add STL_FLAGS= in mozglue/android/Makefile.in. I think this would be the correct fix.
glandium, why do you use cstring and vector into mozglue? x86 compiler use stl-wrapper, but Zip.h uses cstring and vector. So cstring includes mozalloc, so this issue occurs.
comment #4's fix is hack. Correct fix is that mozglue dones't use STL (cstring, vector and etc).

No, the correct fix is that mozglue does no use mozalloc, and "STL_FLAGS=" is the way to do that.
I'd say the ifeq ($(CPU_ARCH),x86) in the patch is unnecessary.
Or, if you want an even more correct way to do it, it would be to fold mozalloc into mozglue, and remove mozalloc dependency on xpcom-config.h. While folding mozalloc into mozglue is in my agenda, it's more work than just adding "STL_FLAGS=", which, again, is a right way to fix this issue.

You don't need that. ANDROID_ARM_LINKER is only needed in mozglue/android for cacheflush, which is arm-specific. Nothing requires ANDROID_X86_LINKER, and nothing will.
