Adam Ford says that DM3730 needs board.c compiled without LTO flags.
Also add clock.c, since it says in Makefile that it need different flags.
I managed to get the am3517_evm tested with the latest series, and it boots just fine.
am3517_evm Without LTO:
SPL 57255 U-Boot 664922
With LTO: SPL 51497 U-Boot 642058
For a reduction in size of: SPL -5758 (-10.06%) U-Boot -22864 (-3.44%)
