You should not need the definition of __STDC_WANT_IEC_60559_BFP_EXT__.  
The point of defining __STDC_WANT_IEC_60559_TYPES_EXT__ here is, I 
presume, to make the compiler-provided float.h define macros for 
_Float128 (_GNU_SOURCE, defined by default, ensures that glibc-provided 
headers declare everything expected for the new type).  The only thing 
__STDC_WANT_IEC_60559_BFP_EXT__ does for the compiler-provided float.h is 
make it define CR_DECIMAL_DIG, which is not used by glibc.

The patch is OK with the definition of __STDC_WANT_IEC_60559_BFP_EXT__ 
removed.
