Makefile: fix linking with pie and binutils > 2.27 

Since binutils 1a9ccd70f9a7[1] TFA will not link when the PIE option is
used:

    aarch64-linux-gnu-ld: build/fvp/debug/bl31/bl31.elf: Not enough room
        for program headers, try linking with -N
    aarch64-linux-gnu-ld: final link failed: Bad value

This issue was also encountered by u-boot[2] and linux powerpc kernel
[3]. The fix is to provide --no-dynamic-linker for the linker. This
tells the linker that PIE does not need loaded program program headers.
