Subject: init/kconfig: Add LD_VERSION Kconfig
X-Git-Tag: rel_imx_5.10.35_2.0.0-somdevices.0~2419^2~4

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.
