xtensa: switch from text-section-literals to auto-litpools
Now that both binutils and gcc support auto-litpools use that option instead of text-section-literals to be able to compile huge functions. Fixes: http://autobuild.buildroot.net/results/dd384fe0ef02a4205bea66a4a16ca2062afe53b4/ http://autobuild.buildroot.net/results/87dd357a4b883ea3cd75546b3d63c4c28245beee/ http://autobuild.buildroot.net/results/b5bca00dec1ecb118c7fb9c10dee74c94809c831/ and many others.
