# Unusual variables checked by this code:
#	NOP - four 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 .ctors .rodata ...
#		(e.g., .PARISC.milli)
#	OTHER_READWRITE_SECTIONS - other than .data .bss .sdata ...
#		(e.g., .PARISC.global)
#	OTHER_SECTIONS - at the end
#	EXECUTABLE_SYMBOLS - symbols that must be defined for an
#		executable (e.g., _DYNAMIC_LINK)
#	TEXT_START_SYMBOLS - symbols that appear at the start of the
#		.text section.
#	DATA_START_SYMBOLS - symbols that appear at the start of the
#		.data section.
#	OTHER_BSS_SYMBOLS - symbols that appear at the start of the
#		.bss section besides __bss_start.
#	DATA_PLT - .plt should be in data segment, not text segment.
#
# When adding sections, do note that the names of some sections are used
# when specifying the start address of the next.
