Major rewrite of how ld is configured. The major idea
is to use shell scripts to generate everything.
* generic.em replaces ldtemplate.
* Other *.em files replace various *.c files.
A *.em file is a shell script that generates the corresponding
ld__*.c file that implements an emulation. This is usually
a straight 'cat' of a here-document, possibly with substitutions.
* Script files (*.sc) are places by *.sc-sh scripts.
Again, these are simple shell scripts that 'cat'
here-documents, usually with some substitutions.
The output a *.sc-sh is a script file.
