This patch adjusts the initialization of __sync built-in functions:
instead of conditionalizing on TARGET_LINUX_ABI, directly place the
target-hook #define in config/nios2/linux.h. This appears to be in line
with other similar ports, e.g. m68k.
Sebastian, this should solve your issue of not wanting __sync_* libcalls
generated on RTEMS (which also uses TARGET_LINUX_ABI due to TLS support),
can you verify it works for you?
