   9 # Besides the shell variables set by the emulparams script, and the LD_FLAG
  10 # variable, the genscripts.sh script will set the following variables for each
  11 # time this script is run to generate one of the linker scripts for ldscripts:
  12 #
  13 # RELOCATING: Set to a non-empty string when the linker is going to be doing
  14 # a final relocation.
  15 #
  16 # CONSTRUCTING: Set to a non-empty string when the linker is going to be
  17 # building global constructor and destructor tables.
  18 #
  19 # DATA_ALIGNMENT: Set to an ALIGN expression when the output should be page
  20 # aligned, or to "." when generating the -N script.
  21 #
  22 # CREATE_SHLIB: Set to a non-empty string when generating a script for
  23 # the -shared linker arg.
