### BUILD OPTIONS
# Any/all of the next three variables may be set to ANYTHING
# that is not null to enable their respective build options
# 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=
# Compile using clang rather than gcc
_clangbuild=
# 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 39.
