[PATCH, AArch64] Handle SYMBOL_SMALL_TPREL appropriately

[Hurugalawadi, Naveen]

Hi Marcus,

Thanks for the review.

>> OK, but fix the trailing white space in the patch

Done. Committed with the modification.

>>  Can you prepare a backport into 4.9

ILP32 support is not completely added in 4.9 and hence the patch
is not needed.

Thanks,
Naveen
