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

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

# PlugApps: Kevin Mihelich <kevin@mihelich>
#  - Added source file for glibc-ports-2.13, needed for building on ARM
#  - Symlink glibc-ports-2.13 source dir to ports dir in glibc directory
#  - Changed configure to enable ports add-on, specify our build host type
