* libc/stdlib/gd_qnan.h (f_QNAN, d_QNAN0, d_QNAN1): Add MIPS
versions.
(ld_QNAN0, ld_QNAN1, ld_QNAN2, ld_QNAN3): Don't define for MIPS.
(ldus_QNAN0, ldus_QNAN1, ldus_QNAN2, ldus_QNAN3, ldus_QNAN4):
Likewise.
* libc/stdlib/ldtoa.c (nan113, nan64, nan53, nan24): Add MIPS
versions.
(enan): Handle legacy MIPS payloads.
* libm/common/s_nan.c (nan): Use __builtin_nan if supported by
the compiler.
* libm/common/sf_nan.c (nanf): Likewise.
