The same two differences as in common/Toolchain.defs: the compiler is told -mfdpic -fPIC, and the module link is done by an arm-uclinuxfdpiceabi linker. That linker is not the one that links the firmware, so the module link needs a variable of its own. CMAKE_ELF_LD is the ordinary linker unless the architecture sets it, which arm does under CONFIG_FDPIC. The linker script needs nothing here: it is generated from libs/libc/elf/gnu-elf.ld.in, which both build systems preprocess, and the FDPIC segments are already in it. -r is now conditional on CONFIG_PIC being off, which is what common/Toolchain.defs has always done and the cmake build did not: a position independent module is linked as an executable, and an FDPIC one as a shared object, so neither wants it. -fno-use-cxa-atexit mirrors CXXELFFLAGS for the same reason it was added there. Configured and built mps3-an547:picostest with CONFIG_FDPIC through cmake and ninja: the modules in bin/ are ARM FDPIC with two PT_LOAD segments.
