# This makefile is a modified Makefile from the openwrt buildroot,
# which in its turn is a modified uClibc Makefile.
# The purpose of this Makefile is to serve as ipkg/rules file
# so an ipkg package can be created using ipkg-build.
# ipkg-buildroot expects stuff in /tmp/package-name, so that's
# where $DESTDIR is set to.

# EDIT this stuff to suit your system and preferences

# Use := when possible to get precomputation, thereby
# speeding up the build process.
