Support Android NDK r14.

simpleperf has moved a little since r13.  To support both, remove its
copy step.

Explicitly disable the Clang integrated assembler on MIPS.  It has only
understood the 'usw' (unaligned store) pseudoinstruction for about 4
months, and that won't be part of a Clang release until the upcoming
Clang 4.0.  Must be that -no-integrated-as was the default in r13.

All six platforms build on my laptop with r14 now.
Will follow up with the CL that moves the bots to r14.
