Michael Brown 987b825b7f [build] Fix building on mildly deranged versions of binutils 
Some versions of binutils have curious concepts of what constitutes
subtraction.  For example:

  0x00000000000000f0 _text16_late = .
  0x0000000000000898 _mtext16 = .
  0x0000000000000898 _etext16 = .
  0x0000000000000898 _text16_late_filesz = ABSOLUTE ((_mtext16 - _text16_late))
  0x00000000000007a8 _text16_late_memsz = ABSOLUTE ((_etext16 - _text16_late))

This has interesting side-effects such as producing sizes for .bss
segments that are negative, causing the majority of addressable memory
to be zeroed out.

Fix by using the form

  ABSOLUTE ( x ) - ABSOLUTE ( y )

rather than

  ABSOLUTE ( x - y )
