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 Signed-off-by: Zakharov Vlad <vzakhar@synopsys.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
