It should be possible to use --without-long-double-128 (if not, that's a 
bug).

If musl has chosen stdint.h types different from those in glibc, you need 
to make the *_TYPE macros appropriately conditional (possibly making 
glibc-stdint.h include conditionals to select the musl types when musl is 
in use).
