When the [p]select syscall returns with an error (eg. EINTR) the timeout
argument is no longer updated.

When 64-bit time_t is supported, the timeout argument is not updated at

    linux: always update select timeout (BZ #27706)
    
    The timeout should be updated even on failure for time64 support.

Title:
  select in gilbc 2.33 does not always set select timeout in Hirsute

Status in GLibC:
  Fix Released
Status in glibc package in Ubuntu:
  Fix Released
Status in glibc source package in Hirsute:
  New

Bug description:
  [Impact]
  * Not updating select's timeout breaks topline's autopkgtest and possibly other software. https://github.com/kilobyte/topline/issues/1

  [Test Plan]

  * Run Groovy's topline's autopkgtest, it should pass:

    $ autopkgtest -U topline_0.3-1.dsc --apt-pocket=proposed=src:glibc
  -- lxd autopkgtest/ubuntu/hirsute/amd64

  [Where problems could occur]

  * The fix removes obsolete checks that prevented updating the returned
  timeout. There are no unexpected side effects from this.
