ARM: 9450/1: Fix allowing linker DCE with binutils < 2.36
commit 53e7e1fb81cc8ba2da1cb31f8917ef397caafe91 upstream.
Commit e7607f7d6d81 ("ARM: 9443/1: Require linker to support KEEP within
OVERLAY for DCE") accidentally broke the binutils version restriction
that was added in commit 0d437918fb64 ("ARM: 9414/1: Fix build issue
with LD_DEAD_CODE_DATA_ELIMINATION"), reintroducing the segmentation
fault addressed by that workaround.
Restore the binutils version dependency by using
CONFIG_LD_CAN_USE_KEEP_IN_OVERLAY as an additional condition to ensure
that CONFIG_HAVE_LD_DEAD_CODE_DATA_ELIMINATION is only enabled with
binutils >= 2.36 and ld.lld >= 21.0.0.
