So even if GLIBC is the master for soft-fp, It is expected that the TF
to KF rename is only in libgcc? And it is Ok for any libm <*>f128
functions that need to call KF versions of soft-fp will link to those
functions in libgcc?
What about any convert functions between TF and KF types (for example
__extendkftf2) Do those only exist in the platform specific libgcc
source or do they need to be included in the soft-fp master source?
