- 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
Mtools is used to format and copy files to vfat partition.
Populatefs is used to copy files to ext4 partition.
Tested on imx6 with u-boot, Generic with BIOS and EFI boot.
To avoid messing around with ext4 partition we could also provide "empty" disk image file. Both partitions would be already formatted and storage partition would already contain resize file. Then mkimage script would only copy kernel, system, bootloader files and install bootloader.
But current approach is more flexible for future use.
