I guess you're trying to use the static libraries generated by the Chromium
build in a different ndk-build based project with PREBUILT_STATIC_LIBRARY.

ndk-build copies prebuilt libraries, this is very useful for debugging with
shared libraries, but there is no good reason to do it with static ones. I'll
file a feature request on b.android.com for this, so we can later get rid of
this.

Can you add links to the bugs digit filed? This sounds mostly like and ndk-build
bug workaround.

Done.
