Subject: Add support for less/greater than comparisons

Was added upstream in 31847b67 (kconfig: allow use of relations other
than (in)equality). Completely unused (and undocumented) in the kernel
except for in DEBUG_UART_8250_WORD in arch/arm/Kconfig.debug:

   depends on DEBUG_UART_8250_SHIFT >= 2

(That line was added before lt/gt support by the way, and assumed a
feature that wasn't there.)

This change (and the upstream one) also slightly changes how
(in)equality comparisons work, making e.g.

  MY_HEX = 0x00037

evaluate to 'y' if MY_HEX is 0x37. Prior to this change, the strings
needed to match exactly.
