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.
