kbuild: check the minimum linker version in Kconfig
Unify the two scripts/ld-version.sh and scripts/lld-version.sh, and
check the minimum linker version like scripts/cc-version.sh did.
I tested this script for some corner cases reported in the past:
- GNU ld version 2.25-15.fc23
as reported by commit 8083013fc320 ("ld-version: Fix it on Fedora")
- GNU ld (GNU Binutils) 2.20.1.20100303
as reported by commit 0d61ed17dd30 ("ld-version: Drop the 4th and
5th version components")
This script show an error message if the linker is too old:
$ make LD=ld.lld-9
SYNC include/config/auto.conf
***
*** Linker is too old.
*** Your LLD version: 9.0.1
*** Minimum LLD version: 10.0.1
***
scripts/Kconfig.include:50: Sorry, this linker is not supported.
make[2]: *** [scripts/kconfig/Makefile:71: syncconfig] Error 1
make[1]: *** [Makefile:600: syncconfig] Error 2
make: *** [Makefile:708: include/config/auto.conf] Error 2
I also moved the check for gold to this script, so gold is still rejected:
$ make LD=gold
SYNC include/config/auto.conf
gold linker is not supported as it is not capable of linking the kernel proper.
scripts/Kconfig.include:50: Sorry, this linker is not supported.
make[2]: *** [scripts/kconfig/Makefile:71: syncconfig] Error 1
make[1]: *** [Makefile:600: syncconfig] Error 2
make: *** [Makefile:708: include/config/auto.conf] Error 2
Thanks to David Laight for suggesting shell script improvements.
