PATCH 1/1 ARM: do not specify -static and -pie at the same time

PIE is a form of dynamic linking and thus inherently incompatible with -static. It worked ok as the current behavior of ld.bfd is to not respect -static if -pie has been specified.

ld.gold and future versions of ld.bfd will fail to link if both of those incompatible switches are specified at the same time.
