Using more recent versions of the Android NDK results in a build failure
saying something like "No toolchains found in the NDK toolchains folder
for ABI with prefix: mips64el-linux-android". Mips support went away
after Android NDK, Revision r17c, and we are using r18b at this moment.
Too old Gradle stuff gets confused by this.
The solution is simple. Use a newer version of the Gradle plugin.
