This could have been done in r359673, but I didn't think I would return
to this function so soon. Lift these macros from arm64 so we don't need
to worry about the size when inserting new elements.
BTW, anyone have a clue how this code works on arm/arm64? It would be good to enable or just remove it here as appropriate.
sys/arm/include/elf.h has the following hint, but it's not clear enough to me:
/* * Magic number for the elf trampoline, chosen wisely to be an immediate * value. */ #define MAGIC_TRAMP_NUMBER 0x5c000003
