[OE-core] [PATCH] qemu-native: set ld.bfd, fix cflags, and set some environment vars

Undefined references to itself, essentially.  Lemme regenerate a build
log with failure in it.  The host toolchain defaults to gcc 5.3.0 with
LTO plugin enabled and gold linker as default (with multilib-strict
profile).  This time I think it's getting confused about
toolchain/binutils multilib config and the qemu makefiles probably
need a bigger set of fixes to work with gold and/or multilib.

My $.02 would be use/set bfd linker as default for now.

Steve

This is without any changes to current poky/oe-core recipes:
