# Generate a linker script for linking the binaries.  This is the
# standard gcc linker script, except hacked so that an alternative
# load address can be specified by (1) asking gcc to use this script
# (-Wl,-T,valt_load_address.lds) and (2) setting the symbol
# valt_load_address to the required value
# (-Wl,-defsym,valt_load_address=0x70000000).
#
# Extract ld's default linker script and hack it to our needs.
# First we cut everything above and below the "=====..." lines at the top
# and bottom.
# Then we have to replace the load address with "valt_load_address".
# The line to replace in has one of the following two forms:
#
#   . = 0x08048000 + SIZEOF_HEADERS;
#
# or
#   PROVIDE (__executable_start = 0x08048000); . = 0x08048000 + SIZEOF_HEADERS;
#
# So we search for the line with a hex value "+ SIZEOF_HEADERS", and replace
# all the hex values in that line with "valt_load_address".
