-# Unusual variables checked by this code:
-# NOP - two byte opcode for no-op (defaults to 0)
-# DATA_ADDR - if end-of-text-plus-one-page isn't right for data start
-# OTHER_READONLY_SECTIONS - other than .text .init .rodata ...
-# (e.g., .PARISC.milli)
-# OTHER_READWRITE_SECTIONS - other than .data .bss .ctors .sdata ...
-# (e.g., .PARISC.global)
-# OTHER_SECTIONS - at the end
-# EXECUTABLE_SYMBOLS - symbols that must be defined for an

-# TEXT_START_SYMBOLS - symbols that appear at the start of the

-# DATA_START_SYMBOLS - symbols that appear at the start of the

-# OTHER_BSS_SYMBOLS - symbols that appear at the start of the

-# DATA_PLT - .plt should be in data segment, not text segment.
-# EMBEDDED - whether this is for an embedded system.

-# When adding sections, do note that the names of some sections are used
