[ARM] 3399/1: Fix link problem when CONFIG_PRINTK is disabled

Patch from Malcolm Parsons

Printking a backtrace requires printk, so disable backtrace code
when printk is disabled.

Without this patch, a kernel with CONFIG_PRINTK disabled does not link:

arch/arm/lib/lib.a(backtrace.o): In function `c_backtrace':
arch/arm/lib/backtrace.S:(.text+0x108): undefined reference to `printk'
arch/arm/lib/backtrace.S:(.text+0x11c): undefined reference to `printk'
arch/arm/lib/lib.a(backtrace.o):(.fixup+0x8): undefined reference to `printk'
