Yaraslau Furman 2e93191001 PKGBUILD: make the kernel build log less verbose
We don't really need to see every single compiled file,
just print the errors and warnings.

vscode also formatted the entire file to remove trailing spaces.

### BUILD OPTIONS
# You can modify these settings by executing "env _<setting>=<value> makepkg"
# instead of modifying the PKGBUILD file. Here's an example:
# env _makemenuconfig=y _copyfinalconfig=y _subarch=30 makepkg
# Tweak kernel options prior to a build via menuconfig.
#
# Set to anything but null to activate.
: "${_makemenuconfig:=""}"
# Tweak kernel options prior to a build via nconfig.
#
# Set to anything but null to activate.
: "${_makenconfig:=""}"
# Tweak kernel options prior to a build via xconfig.
#
# Set to anything but null to activate.
: "${_makexconfig:=""}"
# Use the current kernel's .config file
# Enabling this option will use the .config of the currently
# running kernel rather than the Arch Linux defaults. Useful
# when the package gets updated and you already went through
# the trouble of customizing your config options. NOT recommended
# when a new kernel is released, but again, convenient
# for package bumps.
#
# Set to anything but null to activate.
: "${_use_current:=""}"
# Apply selected optimizations chosen by
# the package maintainers to the config.
#
# Only takes effect if '_use_current'
# is enabled. Keep disabled if you want
# to reuse your existing kernel configuration
# without any changes being applied to it.
#
# Set to anything but null to activate.
: "${_optimize_defconfig:=""}"
# Determines whether the kernel configuration should be
# copied into the source tree before compilation starts.
#
# Set to anything but null to activate.
: "${_copyfinalconfig:=""}"
# Only compile active modules to VASTLY reduce the number
# of modules built and the build time.
#
# To keep track of which modules are needed for your specific system/hardware,
# give modprobed-db a try: https://aur.archlinux.org/packages/modprobed-db
#
# More at this wiki page ---> https://wiki.archlinux.org/index.php/Modprobed-db
# Set to anything but null to activate.

# leave blank, which will require user interaction during the build.
