Serhiy Katsyuba 7bd1953e63 lmdk: Fix linker script
Specifying 0 address for .module section results in few GB binary file.
Instead, put .module section near .text or .rodata.

Guennadi Liakhovetski 2c450e69fa loadable module: don't define PHDR twice
Loadable modules are linked, using a linked script, built by a cmake
script. That linker script includes multiple existing linker script
fragments. Each of those fragments defines 1 or more sections and
respective PHDRs. However, some of those scripts, e.g.
common_rodata_linker_script.txt and data_linker_script.txt add
sections to the same rodata_phdr PHDR. This makes the linker
allocate sections in that PHDR twice in the resulting output file:
one copy is real and the other one is filled with zeros. Removing
one of the PHDR definitions solves the problem and removes about
60KiB of empty space from the output file.

Adrian Warecki 3bd9991121 lmdk: Instruct linker to keep .buildinfo section
At the beginning of the .text section there must be a structure containing
information about the version of the api used by the library. It's absence
will cause sof to interpret a random literal as a version and incorrectly
load a library.

Adrian Warecki 0c2069c2c3 lmdk: Remove content of the .module section from final module image
The .module section contains the module manifest read by rimage. It should
not be included in the final loadable module image. Flags of this section
are now modified using objcopy to ignore it by rimage.

Adrian Warecki d0931d3af5 lmdk: Remove align of .rodata section
The .data and .rodata sections are placed by rimage into one segment of
a resulting firmware image. So aligning the .rodata section to the page
boundary is just a waste of memory.

Adrian Warecki 581cfdf3cc lmdk: Enable linking with standard libraries
Changed linker options to enable linking with libgcc and libc. This change
is required to allow use compiler builtins functions (like __divdi3) and

Andrey Borisovich a675edf8e7 LMDK: fixed rimage and key paths and discovery
Path to rimage and private key had been failing to be used while
provided in form of relative path using dots.
Changed how rimage is discovered in the scripts:
* rimage is searched for using find_program with paths and hints provided
* changed RIMAGE_COMMAND to RIMAGE_INSTALL_DIR so end-user may specify
directory where rimage executable is placed. It will be used by
find_program.
* If RIMAGE_INSTALL_DIR is not provided, find_program will try to
search for rimage in the directory where SOF project installs it
(west_dir/build-rimage).
* Updated README.md with instructions on how to build:
  - simplified configure and build commands
  - updated explanations on how to use RIMAGE_INSTALL_DIR
  - added information on how to use toolchain file
* private key path was parsed incorrectly when provided windows path
style using backslashes. It was passed to rimage as is resulting in the
invalid path as the last slash was made by rimage as forward slash.
Added path normalization what fixed the problem.
