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

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

# ALARM: Kevin Mihelich <kevin@archlinuxarm.org>
#  - removed ada packages
#  - removed gnat (ada stuff) from gcc packaging
#  - disabled make check, too much stress, kills plugs :(
#  - specifid build host, disabled distcc
#  - replaced bugurl with our GitHub issue page
#  - patch to disable LDRD/STRD instructions on ARMv5
