Subject: init/kconfig: Add LD_VERSION Kconfig
X-Git-Tag: v5.10.7~2834^2~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9553d16fa671b9621c5e2847d08bd90d3be3349c;p=platform%2Fkernel%2Flinux-rpi.git

init/kconfig: Add LD_VERSION Kconfig

This option can be used in Kconfig files to compare the ld version
and enable/disable incompatible config options if required.

This option is used in the subsequent patch along with GCC_VERSION to
filter out an incompatible feature.
