[PATCH] Silently ignore grub_file_read when p_filesz == 0

[Kalamatee]

After reading through the ELF specs (http://www.muppetlabs.com/~breadbox/software/ELF.txt) its become clear that a PT_LOAD with p_filesz == 0,is valid - and after checking some elf binaries ive found a number of cases where this is true (including the bootstrap of AROS64)

 

please find a patch enclosed to change the behaviour of multiboot.c's elf loader to silently ignore loading the data if p_filesz == 0
