# Create a toolchain for the Linksys wrt54g
# See http://seattlewireless.net/index.cgi/LinksysWrt54g
#     http://www.batbox.org/wrt54g-linux.html
# Note: recent wrt54g firmware uses uclibc, which behaves like a subsetted glibc.
# There are patches to build uclibc toolchains in the contrib directory,
# but they're not integrated yet.  However, you can still use a glibc
# toolchain; you'll either have to 
#  a) not call the missing functions,
#  b) use a stub library like http://www.xse.com/leres/tivo/downloads/libtivohack/
# or c) link your programs statically if you want them to run on
# the wrt54g.
