	  Object type for llext

config LLEXT_TYPE_ELF_OBJECT
	bool "Single object ELF file"
	help
	  Build and expect object files as binary object type for the
	  llext subsystem. A single compiler invocation is used to

config LLEXT_TYPE_ELF_RELOCATABLE
	bool "Relocatable ELF file"
	help
	  Build and expect relocatable (partially linked )files as the
	  binary object type for the llext subsystem. These object files
	  are generated by the linker by combining multiple object files
	  into a single one.

config LLEXT_TYPE_ELF_SHAREDLIB
	bool "Shared library ELF file"
	help
	  Build and expect shared libraries as binary object type for
	  the llext subsystem. The usual linking process is used to
	  generate the shared library from multiple object files.
