Bring rmodule linking into the common linking method.
The __rmodule_entry symbol was removed while using
a more common _start symbol. The rmodtool will honor
the entry point found within the ELF header. Add
ENV_RMODULE so that one can distinguish the environment
when generating linker scripts for rmodules. Lastly,
directly use program.ld for the rmodule.ld linker script.
BUG=chrome-os-partner:44827
BRANCH=None
TEST=Built rambi and analyzed the relocatable ramstage,
sipi_vector, and smm rmodules.

/*
|
|
* This linker script is used to link rmodules (relocatable modules). It
|
|
* links at zero so that relocation fixups are easy when placing the binaries
|
|
* anywhere in the address space.
|
|
*
|
|
* NOTE: The program's loadable sections (text, module_params, and data) are
|
|
* packed into the flat blob. The rmodule loader assumes the entire program
|
|
* resides in one contiguous address space. Therefore, alignment for a given
|
|
* section (if required) needs to be done at the end of the preceeding section.
|
|
* e.g. if the data section should be aligned to an 8 byte address the text
|
|
* section should have ALIGN(8) at the end of its section. Otherwise there
|
|
* won't be a consistent mapping between the flat blob and the loaded program.
