[PATCH] i386: Fix entry.S code with !CONFIG_VM86

The entry.S code at work_notifysig is surely wrong.  It drops into unrelated
code if the branch to work_notifysig_v86 is taken, and CONFIG_VM86=n.

	[PATCH] Make vm86 support optional
	tree 9b5daef528
	pushed to git Jan 8, 2006, and first appears in 2.6.16

The 'fix' here is to also compile out the vm86 test & branch when
CONFIG_VM86=n.
