* ldmain.c (main): Don't add scriptdir to the lib search path.
* genscripts.sh: Put the scripts in the ldscripts directory, not
emulations.
* configure.in (ldscripts): Make, instead of emulations.
* Makefile.in (scriptdir): Take off the "ld" part.
(install, clean, distclean): Use ldscripts, not emulations.
In tests, pass -L., not -Lemulations.
(ldmain.o): Don't pass -DSCRIPTDIR=....
* ldlang.c (lang_process): Add "ldscripts/" to the name of the
default script file.
