When loading ELF, zero out:
...
The e_shstrndx field in the ELF header, since we don't load .shstrtab.
The sh_name field in each section header, for the same reason.
The sh_offset field for any section we don't load.
This means the kernel has some chance of knowing what it's being given. It
also means that the behaviour of old kernels with new loaders should be
deterministic (if not terribly useful: they still can't find the symbol
table).

When loading an ELF kernel, don't load all the STRTAB sections. Instead, just
...
load those STRTAB sections that are referenced by a SYMTAB that we're loading.
The main advantage of this is that (at least with the binaries output by my
ARM ELF linker) this removes the need to seek backwards through the file, which
is a big win when loading a gzipped kernel.
While we're here, don't allocate space for string tables we don't load.
