It is specific to the few platforms which are exporting __frame_state_for,
which is not all glibc platforms:

$ find /usr/src/libc -name Versions | xargs grep -l __frame_state_for
/usr/src/libc/sysdeps/mach/hurd/i386/Versions
/usr/src/libc/sysdeps/unix/sysv/linux/alpha/Versions
/usr/src/libc/sysdeps/unix/sysv/linux/s390/s390-32/Versions
/usr/src/libc/sysdeps/unix/sysv/linux/arm/Versions
/usr/src/libc/sysdeps/unix/sysv/linux/i386/Versions
/usr/src/libc/sysdeps/unix/sysv/linux/m68k/Versions
/usr/src/libc/sysdeps/unix/sysv/linux/mips/Versions
/usr/src/libc/sysdeps/unix/sysv/linux/powerpc/Versions
/usr/src/libc/sysdeps/unix/sysv/linux/sparc/sparc32/Versions
/usr/src/libc/sysdeps/unix/sysv/linux/sparc/sparc64/Versions

ie. hurd/i386 should include it too, but no other platforms should.
