toolchain: fix aarch64 BE dynamic linker location

Now linaro rootfs picked eglibc-2.19 that contains change that
places aarch64 BE dynamic linker at new location
(/lib/ld-linux-aarch64_be.so.1). But linaro toolchain does not
contain yet corresponding changes and still builds
executable with linker path as /lib/ld-linux-aarch64.so.1.
As result Linaro OE aarch64 BE rootfs is completely broken.

Fix above issue by backporting required changes into binutils
and gcc. One additional patch was required that deals with
differences between 4.8 and 4.9 compiler.
Remove these patches once we get corresponding updates from
upstream.

AArch64-Define-BE-loader-name-default-be.patch
----------------------------------------------

New change. Needed to deal with situation when gcc configured
by default as big endian, i.e no -mbig-endian option is passed.
Note this change is not needed in 4.9 because the following
commit adds -mbig-endian or -mlittle-endian to command line
always. But below commit is too big instead patch deals with
this situation in local "old" way.
