[patch] ARM FreeBSD fix bootstrap

Subject: [patch] ARM FreeBSD fix bootstrap
Authentication-results: sourceware.org; auth=none

Hi all,

the commit for PR68617 broke boostrap on armv6*-*-freebsd*.

We still have unaligned_access = 0 on armv6 here on FreeBSD.

The commit from the above PR overrides my SUBTARGET_OVERRIDE_OPTIONS Icalled in arm_option_override. And it sets the unaligned_access to 1.

The attached patch fixes this, bootstrap ongoing but passed the breakingstage where genmddeps bus errored.


Is this patch ok for trunk once bootstrap completes?

TIA,
Andreas

	* config/arm/freebsd.h (SUBTARGET_OVERRIDE_OPTIONS): Adjust to
	check unaligned_access on the gcc_options set.
	* config/arm/arm.c (arm_option_override): Move
	SUBTARGET_OVERRIDE_OPTIONS from here to
	(arm_option_override_internal).
