Declare strtof, strfromf functions for more _FloatN, _FloatNx types.
Continuing the preparation for additional _FloatN / _FloatNx type support, this patch arranges for <stdlib.h> to declare strtof and strfromf functions for all such types, similarly to the declarations already present for _Float128. Tested for x86_64. * stdlib/stdlib.h [__HAVE_FLOAT16 && __GLIBC_USE (IEC_60559_TYPES_EXT)] (strtof16): Declare. [__HAVE_FLOAT32 && __GLIBC_USE (IEC_60559_TYPES_EXT)] (strtof32): Likewise.
