[PR87833] x86: Put -fPIC and -shared the last to create offload image

On x86, since -fPIC and -shared should be used to create offload image,
we put them the last to properly create offload image.

	PR target/87833
	* config/i386/intelmic-mkoffload.c (prepare_target_image): Put
	-fPIC and -shared the last to create offload image.

Backport from trunk r278041.
