Partially disabled glibc ioctls causing FTBFS error(s)
I just noticed the inetutils build failure on the Hurd, and tracking
it down found:
While I've prepared a patch to fix this, I think it might be better
(instead or in addition) to disable the ioctls and the matching ioctl
For example in inetutils, the code works on GNU/Linux because it's
checking whether LNOFLSH is defined, and if so then it uses TIOCLGET.
