ld: implement -ztype and rework option parsing

*** 1541,1551 ****
           *      reductions are being processed.
           *
           *  -   the -Bsymbolic flag is in use when building a shared object,
           *      and the symbol hasn't explicitly been defined as nodirect.
           *
!          *  -   an executable (fixed address) is being created, and the symbol
           *      is defined in the executable.
           *
           *  -   the relocation is against a segment which will not be loaded
           *      into memory.  In this case, the relocation must be resolved
           *      now, as ld.so.1 can not process relocations against unmapped
