PROGRAM_DESCRIPTION=\
"Rebuild the gdbserver prebuilt binary for the Android NDK toolchain.
Where <src-dir> is the location of the gdbserver sources,
<ndk-dir> is the top-level NDK installation path and <toolchain>
is the name of the toolchain to use (e.g. arm-linux-androideabi-4.4.3).
The final binary is placed under:
<ndk-dir>/toolchains <toolchain>/prebuilt/gdbserver
NOTE: The --platform option is ignored if --sysroot is used."
