Ah, thanks for that.  Good to see soeone giving glibc a run for it.

I looked a bit more at glibc.  They say never to include
<sys/ttydefaults.h> directly.  Only to be included when BSD and SYSV
compatibilty is selected.  Since gpsd is baselined on C99 and POSIX-1:2001
that is not something to be added easily.

Check the bottom of termios.h to see if that is true, and maybe someone
has the wrong CFLAGS set.
