Thanks Gaby...
To recap, my current quest is to resolve references to symbols like
__floatdidf. This is in a library for ppc64/soft-float.
Ian pointed me to ppc64-fp.c. When I try to compile it, TFtype is
undefined. It is suppose to get defined in fp-bit.h but only if
__LDBL_MANT_DIG__ is set to 113 or 106. Right now, in the
environment that I have now, ___LDBL_MANT_DIG__ is set to 53. In the
RS/6000, long doubles are 106. (I'm not sure if "long double" is the
right term to use here.)
I am compiling with -maix64. It appears to me that some parts of gcc
or libgcc assume that this implies long double but c-cppbuiltin.c
appears to not make that assumption.
I'm not sure where or how to address this issue.

a built-in macro. See gcc/c-cppbuiltin.c
