x86/build: Use the single-argument OUTPUT_FORMAT() linker script command

The various x86 linker scripts use the three-argument linker script
command variant OUTPUT_FORMAT(DEFAULT, BIG, LITTLE) which specifies
three object file formats when the -EL and -EB linker command line
options are used. When -EB is specified, OUTPUT_FORMAT issues the BIG
object file format, when -EL, LITTLE, respectively, and when neither is
specified, DEFAULT.

However, those -E[LB] options are not used by arch/x86/ so switch to the
simple OUTPUT_FORMAT(BFDNAME) macro variant.

No functional changes.
