disable GAS overflow check for Xtensa

I have applied this patch to fix a fairly obscure problem in the Xtensa port of GAS that only seems to occur when assembling a really large section of code. The patch disables the generic overflow checking, which isn't needed anyway because the Xtensa code does its own overflow checks.
