common: Add symbol handling for generic lists into Makefile
This patch adds essential components for generation of the contents of
the linker section that is used by the linker-generated array. All of
the contents is held in a separate file, u-boot.lst, which is generated
at runtime just before U-Boot is linked.
The purpose of this code is to especially generate the appropriate
boundary symbols around each subsection in the section carrying the
linker-generated arrays. Obviously, the interim linker code for actual
placement of the variables into the section is generated too. The
generated file, u-boot.lst, is included into u-boot.lds via the linker
INCLUDE directive in u-boot.lds .
Adjustments are made in the Makefile and spl/Makefile so that the
u-boot.lds and u-boot-spl.lds depend on their respective .lst files.
