Title:
  klibc ftbfs in eoan

Status in klibc package in Ubuntu:
  Fix Released
Status in klibc source package in Eoan:
  Fix Committed

Bug description:
  [ SRU Justification / Impact ]
  klibc is FTBFS in eoan.  As we have a history of SRUing klibc to add new features, we should probably make sure it's buildable.

  [ Test Case ]
  If it builds, we win.  Should also test that a machine with the new klibc installed still boots.

  [ Regression Potential ]
  One patch is just adding a missing include, and the other is altering the build of a stub only used to determine which syscalls are availble, a part of the build that will cause the rest of the build to fail if it's generated incorrectly.  Regression potential should be very low.
