[Qemu-devel] [PATCH v2 3/5] build: do not use TARGET_ARCH

[Paolo Bonzini]

TARGET_ARCH is generally wrong to use, there are better variables
provided in config-target.mak.  The right one is usually TARGET_NAME
(previously TARGET_ARCH2), but for bsd-user we can also use TARGET_ABI_DIR
for consistency with linux-user.
