PR27226, ld.bfd contains huge .rodata section
This makes it possible to build ld without any compiled-in scripts,
by setting COMPILE_IN=no in the environment. pe, beos and pdp11
targets didn't support scripts from the file system, with pdp11
nastily editing the ld/ldscripts file so that the built-in script
didn't match.
