[PATCH] RTEMS: Add -ftls-model=local-exec to multilibs

[Sebastian Huber]

Use the local-exec TLS model for all multilibs of all RTEMS targets with proper
TLS support.

gcc/ChangeLog:

	* config/arm/t-rtems (MULTILIB_EXTRA_OPTS): Define to use
	-ftls-model=local-exec.
	* config/i386/t-rtems (MULTILIB_EXTRA_OPTS): Likewise.
	* config/m68k/t-rtems (MULTILIB_EXTRA_OPTS): Likewise.
	* config/microblaze/t-rtems (MULTILIB_EXTRA_OPTS): Likewise.
	* config/nios2/t-rtems (MULTILIB_EXTRA_OPTS): Likewise.
	* config/riscv/t-rtems (MULTILIB_EXTRA_OPTS): Likewise.
	* config/rs6000/t-rtems (MULTILIB_EXTRA_OPTS): Likewise.
	* config/sparc/t-rtems (MULTILIB_EXTRA_OPTS): Likewise.
