# -- Perform a static build of gdbserver (gdb-7.12)
#
# This was designed particularly to demonstrate the way
# that the activate scripts can be used and assumes you sourced
# the appropriate one before running this script. You can use
# them for for toolchains built by the excellent musl-cross-make
# tool:
#
#   https://github.com/richfelker/musl-cross-make
# 
# It also works fine with the OpenWRT toolchains that are
# available prebuilt:
#
#   https://downloads.openwrt.org/snapshots/trunk
#
# The easiest way to make this work without modification is
# to use one of the toolchain activation scripts in this
# repository. Otherwise you will need to set up stuff yourself
# like the path to libstdc++.a, libgcc_eh.a and the --host
# parameter. Hopefully you can figure out how to do this
# manually anyway if you're planning on debugging native
# code on another architecture, but this makes it easier
