needs.
# Set these variables to suit your needs

for example, "windows-x86" or "linux-x86_64" or "darwin-x86_64"}
TOOLCHAIN_VERSION={"4.8", "4.9", "clang3.5", etc. This corresponds to a
toolchain directory under ${NDK_PATH}/toolchains/.}

"16", "19", etc.}

If building for Android 4.0.x (API level < 16) or earlier, remove `-fPIE` from
`CFLAGS` and `-pie` from `LDFLAGS`.
