make.conf used on rpi4 / Rock64 Pro (USER Necrose99) some bits swiped from Sabayon. for modularity.

1. These settings were set by the catalyst build script that automatically
2. built this stage.
3. Please consult /usr/share/portage/config/make.conf.example for a more
4. detailed example.

2. some of my greatest hits... granted i need to cleave much in this use flags repo.

USE_PYTHON="3.6"

PYTHON_TARGETS="python2_7 python3_6 python3_7 python3_8 python3_9"

1. mgorny python hack tip. can force for newer 36 py.. etc.. if i get wind of coming py34 deprication
   1. python-3.5 tending to fuck with crap on rpi3-64 , server not so bad since newer ver.
   2. PYTHON_COMPAT_OVERRIDE='pypy3'
2. pypy pypy3 wont build on 2 gigs+++ =< RPI3 has a gig.

1. Some more forced targets
2. update me .. PHP_TARGETS="php5-6"

RUBY_TARGETS="ruby25 ruby26 ruby27"

1. ruby24 fails to comiple on rpi3 perhaps on Bannanpi64 or with more RAM, it will sit on R-PI3 for dayz....

1. https://github.com/gentoo/dotnet layman -a dotnet

DOTNET_TARGETS="net45 net40 net50 net60"

1. Setup GRUB platforms

GRUB_PLATFORMS="arm arm64"

1. Support both 64bit and 32bit

ABI_arm64="arm64 arm32 lp64 lp32" ## would be a plus.

1. 1. PORTAGE CONFIG ##
   2. PORTDIR_OVERLAY="/usr/local/portage"

PORTDIR_OVERLAY="/var/lib/layman/"

1. source /var/lib/layman/make.conf

CONFIG_PROTECT="/usr/share/config/kdm /etc /etc/conf.d /etc/init.d"

1. /lib/modules mask is useful for our internal tinderbox

CONFIG_PROTECT_MASK="/etc/skel /lib/modules"

1. Set PORTDIR for backward compatibility with various tools:
2. gentoo-bashcomp - bug #478444
3. euse - bug #474574
4. euses and ufed - bug #478318

1. 1. xpak sometimes are usable othertimes metadata, dont sftp cleanly...
