  IHMO it is quite dirty... Normally such a symbol is defined
 in the linker command file, like "_etext" and "_end".
 I begin to understand why there is only the linker option
 "--sort-common" and not "--sort-data" or even "--sort-code",
 which would save more and more space because alignment
 requirement are getting bigger and bigger.

  Also, emacs linker pass is order dependant for .o/.a files.

  I would just like the possibility to do it, having to add an
 option is not a problem (I already have 15 options only for the
 compiler - not counting preprocessor or linker options).
