x86/EFI: work around CFLAGS being passed in through environment

Short of a solution to the problem described in
http://lists.xen.org/archives/html/xen-devel/2012-12/msg00648.html,
deal with the bad effect this together with c/s 25751:02b4d5fedb7b has
on the EFI build by filtering out the problematic command line items.
