Link targets that need RRC ASN.1 headers to header-only library

Most targets don't need the symbols from the compiled RRC ASN.1
libraries, but only the headers. In particular when compiling individual
libraries (e.g., for tests), linking the full library makes the RRC
ASN.1 libraries compile and link, when they are not needed (only headers
are needed).

For libraries that can do without these headers, don't link them.
