Notes:
v2:
- Addressed comments from Thomas.
- Tested on ARM target and on x86_64 with qemu.

v3:
- set CONFIG_CHECKPOINT_RESTORE in kernel config
- Only be available for ARMv6, ARMv7 and ARMv8

v4:
- set SUBARCH for armv6, armv7 and armv8
- Use github download helper

Result from test-pkg:
bootlin-armv5-uclibc [1/6]: SKIPPED
bootlin-armv7-glibc [2/6]: OK
bootlin-armv7m-uclibc [3/6]: SKIPPED
bootlin-x86-64-musl [4/6]: OK
br-arm-full-static [5/6]: SKIPPED
sourcery-arm [6/6]: SKIPPED
6 builds, 4 skipped, 0 build failed, 0 legal-info failed, 0
show-info failed

v5:
- Remove support for s390 arch
- Depend on BR2_HOST_GCC_AT_LEAST_8
- Depend on BR2_TOOLCHAIN_HEADERS_AT_LEAST_4_18
- Depend on !BR2_TOOLCHAIN_USES_UCLIBC
- Use BR2_NORMALIZED_ARCH instead of BR2_ARCH
