build with clang
# Maintainer: graysky <graysky AT archlinux DOT us>
# Contributor: Jan Alexander Steffens (heftig) <jan.steffens@gmail.com>
### BUILD OPTIONS
# Set the next two variables to ANYTHING that is not null to enable them
# Tweak kernel options prior to a build via nconfig
_makenconfig=
# Only compile select modules to reduce the number of modules built
#
# To keep track of which modules are needed for your specific system/hardware,
# give module_db a try: https://aur.archlinux.org/packages/modprobed-db
# This PKGBUILD reads the database kept if it exists
# More at this wiki page ---> https://wiki.archlinux.org/index.php/Modprobed-db
_localmodcfg=
# Optionally select a sub architecture by number or leave blank which will
# require user interaction during the build. Note that the generic (default)
# option is 36.
