I was thinking proposing a patch similar to that, but I was intended to instead
to add a new implied folder to propose something like that:

#include <math_ldbl_opt.h>
#if __WORDSIZE == 64
#include <sysdeps/ieee754/dbl-64/wordsize64/s_isnan.c>
#else
#include <sysdeps/ieee754/dbl-64/s_isnan.c>
#endif
#ifndef IS_IN_libm
# if LONG_DOUBLE_COMPAT(libc, GLIBC_2_0)
compat_symbol (libc, __isnan, __isnanl, GLIBC_2_0);
compat_symbol (libc, isnan, isnanl, GLIBC_2_0);
# endif
#endif

But your idea to add a folder seems more flexible.
