external/oprofile/libpp/format_output.h:94:22: error: reference ‘counts’ cannot be declared ‘mutable’ [-fpermissive] 
make: *** [out/host/linux-x86/obj/STATIC_LIBRARIES/liboprofile_pp_intermediates/arrange_profiles.o] Error 1 
解决办法： 
external/oprofile/libpp/format_output.h 

把： 
mutable counts_t & counts; 
改为： 
counts_t & counts;
