gcc: More places to patch to disable ldbl 128 for musl on PPC
There are four functions using TFmode type (128bit) that isn't available when building with musl. Move each of them from common ppc64-fp.c to individual files referenced from t-float128 that used when ldbl 128 enabled at configure time. For gcc-7.3 if -mfloat128 is given -mfloat128-type must be given too. Exclude ibm-ldouble.c when ldbl 128 isn't enabled at config time. Build and boot tested with musl (no float128) and glibc (float128 and ibm128 on PowerPC64). (From OE-Core rev: dec8e566810525563b33c2877d10db0a70965d6d) Signed-off-by: Serhey Popovych <serhe.popovych@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
