Rich Felker c94a0c16f0 isatty: don't collapse all non-EBADF errors to ENOTTY 
linux puts hung-up ttys in a state where ioctls produce EIO, and may
do the same for other types of devices in error or shutdown states.
such an error clearly does not mean the device is not a tty, but it
also can't reliably establish that the device is a tty, so the only
safe thing to do seems to be reporting the error. programs that don't
check errno will conclude that the device is not a tty, which is no
different from what happens now, but at least they gain the option to
differentiate between the cases.

commit c84971995b introduced the errno
collapsing behavior, but prior to that, errno was not set at all by
isatty.

    musl libc

musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.

The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.

For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
the project website:
