# This script uses the build script to create a glibc based mips native
# GCC package.  Set TOPDIR and TARGET before running.  TOPDIR should be
# The directory where you want to build everything (it will contain subdirs
# for sources, objects, etc) and TARGET should be
# mipsisa32r6el-unknown-linux-gnu or something like that.
#
#	Targets I have built with this script:
#
#		mipsisa32r6el-unknown-linux-gnu
#		mipsisa64r6el-unknown-linux-gnu
