The files in this directory are ld linker scripts.
They were produced apparently by the scripttmpl shell scripts 
included with the ld source.
genscripts.sh sets some shell variables, then sources
EMULATION.sc, to generate EMULATION.{x,xr,xu,xn,xbn} -- the script
files for default, -r, -Ur, -n, -N.

Thus elf_i386.x  seems to be the default ELF script, which ld seems
to be able to operate without anyway, if my strace'ing is to be believed.
