[PATCH] Centralize Linker Symbols
Richard Henderson point out a while back that linker generated symbols
should be declared as: "char _text[]" so that the compiler can't make
assumptions about them sitting in small sections, etc.
Centralize these defintions in asm/sections.h (where some already
are on x86).
