Answer 1

Android bundles the simpleperf tool which is almost a drop-in replacement for many usages of perf/linux-tool-perf.

Answer 2

Have you looked at external/linux-tools-perf/ inside android repository?

Answer 3

the error clearly says , you need select appropriate value while exporting ,

export NDK_TOOLCHAIN=${NDK}/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86/bin/arm-linux-androideabi-

should be

export NDK_TOOLCHAIN=${NDK}/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86/bin/arm-linux-androideabi-4.6

If it dosen't work , i recommend you recheck the overall path which $NDK_TOOLCHAIN contains.
