- replace strip_lto/strip_gold (only allowed to disable) - add flag for PIC feature - add flag to stop build parallel - add support for hardening option (initial copy from debian 9) All build parameters, are added in setup_toolchain. `PKG_[FLAG]_[HOST/TARGET]_ENABLED` variable is introduced for checking the flag (yes/no) in the package.mk Thanks to @MilhouseVH, for support and fixing
