elflink: ldlinux should not have any dependencies
ldlinux currently requires the get_key() symbol, which means it has a dependency on libutil_com.c32. ldlinux.c32 really should be a standalone module so let's move get_key.c into ldlinux/. However, moving get_key.c creates a new problem - native linux applications such as com32/samples/keytest.c require the get_key() symbol which is currently exported by libutil_lnx.a. To fix this, we create a new native linux library that exports any required symbols from ldlinux. With this change we need to update com32/Makefile so that we build com32/elfink/ldlinux before com32/samples, and seeing as ldlinux now has no dependencies, we may as well move it to the front of $SUBDIRS. Also, update elf_gen_dep.sh to skip ldlinux.c32 and not search for dependencies for any of its unresolved symbols. This way, if anyone inadvertently introduces a dependency that cannot be resolved by the core, ldlinux.c32 will fail to load at runtime (which guarantees that the newly introduced dependency won't go unnoticed).
