uboot: Use "mdbtrick" target when building elf for ARC
By default position independent executables (PIE) are generated
when building U-Boot elf target. MetaWare debugger doesn't support
PIE (position-independent executable).
In order to allow MDB load and run U-Boot elf, we need to do a
special trick, called "mdbtrick".
This special build target is used to fake generated U-Boot elf by:
1. Reset PIE flag in ELF header
2. Strip all debug information from elf
