pr82748-1.c is another victim of this issue.  do_copysign_ld needs to convert
between (64-bit) long double and __ieee128 for __builtin_copysignq, and since
the expanders for these conversions are conditioned on TARGET_LONG_DOUBLE_128,
we end up issuing libcalls, but the test doesn't want any 'bl' opcode.
