[IA64] Add __mca_table to the DISCARD list in gate.lds

Add __mca_table to the DISCARD list for the gate.lds linker script to avoid broken linker references when linking the final vmlinux file. Also add comment to include/asm-ia64/asmmacros.h to avoid anyone else hitting this problem in the future.
