# Maintainer: Allan McRae <allan@archlinux.org>

# toolchain build order: linux-api-headers->glibc->binutils->gcc->binutils->glibc
# NOTE: valgrind requires rebuilt with each major glibc version

# ALARM: Kevin Mihelich <kevin@plugapps.com>
# - Added source file for glibc-ports, needed for building on ARM
# - Symlink glibc-ports source dir to ports dir in glibc directory
# - Changed configure to enable ports add-on, specify our build host type
# - Disabled distcc and ccache, make -j1 for v5, -j2 for v7
