Subject: [PATCH] libgcc: Enable XF mode conversions to/from DFP modes only if
supported
Some targets do not support XF mode (eg AArch64), so don't build the
corresponding to/from DFP modes convertion routines if
__LIBGCC_HAS_XF_MODE__ is not defined.

* _dd_to_xf.c: Check __LIBGCC_HAS_XF_MODE__.
* _sd_to_xf.c: Likewise.
* _td_to_xf.c: Likewise.
* _xf_to_dd.c: Likewise.
* _xf_to_sd.c: Likewise.
