powerpc64-linux infrastructure 4 of 6

[Alan Modra <amodra at bigpond dot net dot au>]

Yet more infrastructure.

ld/ChangeLog
	* genscripts.sh: Source the emulparams script before each output
	script is generated so that variables like `RELOCATING' may affect
	variables defined in the emulparams script.

Applying to mainline.
