Subject: [PATCH] [2/5] kbuild: Check if linker supports the -X option


The new alternative `gold' linker in recent binutils doesn't support
the -X option. This breaks allyesconfig builds that have 
CONFIG_STRIP_ASM_SYMS enabled. Check if the linker really supports
the option using ld-option.

This requires fixes in earlier patches.
