When building a multi_v7_defconfig kernel it is not possible to configure DEBUG_LL to use any serial device except a ARM Primecell PL01X, or more accurately and worse, it is possible to configure a different serial device but KConfig does not honour this request.
The happens because the multi-platform mode may include ARCH_SPEAR13XX and this forcibly engages DEBUG_UART_PL01X to provide some kind of compatibility with single platform builds (SPEAr supports both single and multi-platform). This in turn causes DEBUG_LL_INCLUDE to wedge at debug/pl01x.S.
Problem is fixed by only deploying the compatibility options for SPEAr when ARCH_MULTIPLATFORM is not set.
The assumption is actually wrong: SPEAr does not support single platform builds any more. The PLAT_SPEAR_SINGLE symbol in Kconfig is a leftover from an earlier patch I did that never got merged, and we should just remove that.

Removing the SPEAR lines seems correct here, but the lines you add don't make any sense.
