Glibc 2.28 Upstream Will Build/Run Cleanly On GNU Hurd

While Linux distributions are still migrating to Glibc 2.27, in the two months since the release changes have continued building up for what will eventually become the GNU C Library 2.28.

The Glibc 2.28 work queued thus far isn't nearly as exciting as all the performance optimizations and more introduced with Glibc 2.27, but it's a start. Most notable at this point for Glibc 2.28 is that it will now build and run cleanly on GNU/Hurd without requiring any out-of-tree patches. There has been a ton of Hurd-related commits to Glibc over the past month.

Glibc 2.28 also no longer installs the libio.h header file, stdio functions now treat end-of-file as a sticky condition, and math.h has added functions that round their results to a narrower type. More details on the tentative changes so far for Glibc 2.28 can be found via the work-in-progress NEWS and via their Git repo in general.
