Add linker flags when linking kernel.exec to have malloc and free point to grub_malloc and grub_free respectively. Some gdb functionality depends on gdb locating the symbols "malloc" and "free", such as dynamically creating strings for arguments to injected function calls. A trivial example would the gdb command 'p strlen("astring")'.
