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
