The Cortex A8 hardware apparently has a bug which ld.gold will try to
correct; however in order to do so it must have unstripped executables
lest we see warnings of the form (see #10376, #10464),

    /usr/bin/ld.gold: warning: cannot scan executable section 1 of ...
    for Cortex-A8 erratum because it has no mapping symbols.

Consequently we disabling stripping by default on this architecture.

A bit more discussion about this issue can be found in this [Android
issue](http://code.google.com/p/android/issues/detail?id=40794).

Test Plan: Try validating on ARM
