Yes, some buildfarm machines caught that already.  Here is the commit
fixing it, which will be available in next week's round of minor
releases:

Rename pg_rewind's copy_file_range() to avoid conflict with new linux syscall.

Upcoming versions of glibc will contain copy_file_range(2), a wrapper
around a new linux syscall for in-kernel copying of data ranges. This
conflicts with pg_rewinds function of the same name.

Therefore rename pg_rewinds version. As our version isn't a generic
copying facility we decided to choose a rewind specific function name.

Per buildfarm animal caiman and subsequent discussion with Tom Lane.

Backpatch: 9.5-, where pg_rewind was introduced

This report reminds me that I haven't patched yet the version of
pg_rewind for REL9_4_STABLE and REL9_3_STABLE that I maintain for
VMware.  Will do that now..
