By taking the extendhftf2.c and adapting it to cosmopolitan libc code like this:

//===-- lib/extendhftf2.c - half -> quad conversion ---------------*- C -*-===//

#define QUAD_PRECISION
#include "third_party/compiler_rt/fp_lib.inc"

#define SRC_HALF
#define DST_QUAD
#define tf_float long double
#include "third_party/compiler_rt/fp16_extend_impl.inc"

COMPILER_RT_ABI dst_t __extendhftf2(src_t a) {
    return __extendXfYf2__(a);
}

The linker error goes away.
