935a0041ac UPSTREAM: rmodtool: correct final memory size calculation 
Apparently when I originally wrote this I confused myself to no end.
The code/data of an rmodule has a set memory size which is associated
with the .payload section. The relocation entries may increase the
overall footprint of the memory size if the rmodule has no bss but
a lot of relocations. Therefore, just compare relocation entries size
plus the file size of the .payload section with the memory size of the
paylod section. The .empty section is added only when we have not met
the final target size.

TEST=Compiles successfully and the elf.rmod created is verified using readelf
and objdump

a642102ba7 rmodtool: add support for ARM 
Add support for creating ARM rmodules. There are 3 expected
relocations for an ARM rmodule:
- R_ARM_ABS32
- R_ARM_THM_PC22
- R_ARM_THM_JUMP24

R_ARM_ABS32 is the only type that needs to emitted for relocation
as the other 2 are relative relocations.

BUG=chrome-os-partner:27094
BRANCH=None
TEST=Built vbootstub for ARM device.
