 config.mk.in: Disable stripping by default on ARM

 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
