sys/endian.h: No such file or directory

[GitHub issues - opened]

alsa-project/alsa-lib issue #522 was opened from FuwwyCodingCOwO:

It seems that GNU/Hurd does not have `sys/endian.h`, this could probably be fixed by instead using `endian.h` provided by [POSIX](https://pubs.opengroup.org/onlinepubs/9799919799/basedefs/endian.h.html). The [Hurd porting guidelines](https://www.gnu.org/software/hurd/hurd/porting/guidelines.html) seem to agree with this. I will make a pull request to go along with this.
