Patch libgcc to always use _Float128 and _Complex _Float128 on PowerPC.
2022-11-09 Michael Meissner <meissner@linux.ibm.com>
libgcc/
* config/rs6000/quad-float128.h (TF): Delete definition.
(TFtype): Define to be _Float128.
(TCtype): Change to be _Complex _Float128.
* libgcc2.h (TFtype): Allow MD code to override definition.
(TCtype): Likewise.
* soft-fp/quad.h (TFtype): Likewise.
