Use the local-exec TLS model for all multilibs of all RTEMS targets with proper
TLS support.
gcc/ChangeLog:
* config.gcc (aarch64-*-rtems*): Extend tmake_file.
* 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.
* config/aarch64/t-aarch64-rtems: New file.
---
v2:
* Include aarch64. This required a new RTEMS-specific file.
