magic to converts scripts, since that is now handled
by genscripts.sh and the *.sc-sh scipt generators.
* config.h: Remove a bunch of macros defining emulations
and targets. This becomes one less file to edit when
adding emulations or targets.
* ldemul.h (struct ld_emulation_xfer_struct): Add
emulation_name and target_name fields.
* ldemul.c, ldemul.h: Define some default functions used
by most emulations (and remove from the *.em scripts).
* ldemul.c (ldemul_choose_target): Search the new
ld_emulations array using a loop (instead of a hardwired
nested if statement).
Define the ld_emulation from the automatically-geenrated
ldemul-list.h. This means you no longer have to edit ldemul.c
to add a new emulation.
* ldmain.c: Replace {GLD,LNK}960_EMULATION_NAME by
their expansions, since the former no longer exist.
* PORTING: A very rough first draft of a porting guide.
