4 Subject: config.mk: move LDSCRIPT processing to the top-level Makefile
6 Upstream-Status: Accepted
8 LDSCRIPT is used only from the top-level Makefile and only when the
9 system is configured so we can move LDSCRIPT and CONFIG_SYS_LDSCRIPT
10 related logic into the top level Makefile and under configured condition
11 to avoid errors when building tools from unconfigured tree.
