Subject: In the absence of a linker to build the GOT, use the 32-bit
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=ec867a22b3b3e131187e105b3639bcf5eb101590;p=oota-llvm.git

In the absence of a linker to build the GOT, use the 32-bit
non_lazy_ptr mechanism on x86-64 Darwin JIT.  Fixes a bunch
of last night's failures.
