Let the user change the dynamic linker used by ELF code.
* ld.h (args_type): Add new field interpreter.
* lexsup.c (parse_args): Add dynamic-linker to longopts, and
handle it.
* ldmain.c (main): Initialize command_line.interpreter to NULL.
* emultempl/elf32.em (gld${EMULATION_NAME}_before_allocation): Get
the ELF backend to return the .interp section. If
command_line.interpreter is not NULL, set the contents of .interp
to it.
* ld.texinfo: Mention -dynamic-linker.
