+
+ * Makefile.in (GENSCRIPTS): Pass the default emulation name to
+ genscripts.sh. Pass the current emulation name without ".sh" on
+ the end.
+ * genscripts.sh: Take an default emulation arg.
+ Use the emulparams file name as EMULATION_NAME.
+ Make default lib path for cross-compiling ':', not null.
+ * emulparams/*.sh: Don't set EMULATION_NAME.
+ * ldemul.c (ldemul_get_script): Take isfile arg.
+ Pass it to emulation's get_script function.
+ * ldemul.h: Adjust get_script prototypes.
+ * ldfile.c (ldfile_find_command_file): Renamed from find_a_name.
+ No longer static.
+ * ldfile.h: Declare it.
+ * ldgram.y: Accept a script on the command line again,
+ for parsing compiled-in scripts.
+ * ldmain.c (main): If ld script is a file, parse it as a -T
+ option, otherwise parse it directly.
+ * emultempl/*.em (*get_script): Return the scripts themselves if
+ this is the default emulation; otherwise return their file names.
+ * emultempl/m88kbcs.em: New file, to take m88kbcs.em #ifdef out of
+ generic.em.
+ * emulparams/m88kbcs.sh: Use it.
+
+ * ld.h (unix_relocate): Remove unused var.
