Makefile: Fix linking with modern binutils

Since Binutils 1a9ccd70f9a7[1] u-boot will not link targets that set
CONFIG_SYS_TEXT_BASE=0 with the following error:

  LD      u-boot
arm-linux-gnueabi-ld.bfd: u-boot: Not enough room for program headers, try
 linking with -N
arm-linux-gnueabi-ld.bfd: final link failed: Bad value

The issue can be reproduced with the bad binutils and the rock2_defconfig
target.

This issue was also encountered by the powerpc kernel[2], with the fix
being to pass --no-dynamic-linker for linkers newer than 2.26 when this
flag was introduced. The option tells ld that the PIE or shared lib does
not need loaded program headers.

Ubuntu Zesty's Binutils 2.27.51.20161202 hits this error.
