fix Xtensa --text-section-literals option for GNU/Linux

It appears that I broke the Xtensa assembler's --text-section-literals option 
for GNU/Linux over a year ago.  I changed the linker to require that all dynamic 
relocations be inside marked literal pools, but the assembler has not been 
marking those literal pools when using the --text-section-literals option.  This 
patch simply changes gas to always mark the literal pools.  Tested by linking a 
small program built with --text-section-literals for an xtensa-linux target, and 
also by running the testsuite for an xtensa-elf target.  Committed on the mainline.

	* config/tc-xtensa.c (xtensa_post_relax_hook): Generate literal tables
	even when using the text-section-literals option.
