bsp/tms570: Add -mbe32 to LINKFLAGS
There is not just big-endian on ARM. We have two variants BE32
(obsolete) and BE8. The Cortex-R5F processor supports only BE8,
however, some TMS570 variants are BE32 internally. In GCC 8 and later,
the --be8 option is passed to the linker based on the selected
architecture or CPU. Use BE32 by default for the TMS570 BSP.
In GCC, see:
