No toolchains found in the NDK toolchains folder for ABI with prefix: mips64el-linux-android #599

@codeanticode,
Recently faced this issue when I again setup my Processing PDE and Android-mode,
when I dig deep into this issue, I found that this issue is caused by building an app from PDE using android-mode and our gradle-build-tools that we are using in basic app templates (TopBuild.gradle.tmpl ) for app generation is 3.0.1, and i found an answer for temporary solution here

But for permanent solution we have to upgrade our build-tool's version to latest and also upgrade the basic build templates to latest version.
