remove all references to .dynsym

Browse source 
Discard all .dynsym sections from linker scripts
Remove all __dynsym_start definitions from linker scripts
Remove all __dynsym_start references from the codebase

Note: this touches include/asm-generic/sections.h, which
is not ARM-specific, but actual uses of __dynsym_start
are only in ARM, so this patch can safely go through
the ARM repository.
