Message:

Read symbol table from ELF sections

Instead of the currently broken data generated using genmap.py,
read the ELF symbol table for stack traces and symbol names.
In addition to that, prepare ground for accessing DWARF debug
sections.

Because neither .symtab, nor .debug_* sections are
normally part of the program image, these have to be provided
externally. Instead of the previous way of relinking kernel
to bake in the symbol data, we now only link kernel once
and the extra debug data is loaded as part of the initrd image.
