This change breaks compiling the latest git coreutils on at least cygwin:

GNU gperf 2.7.2

gperf is not on the list of widely available programs, so it must not be 
invoked by a normal user when compiling a tarball, but requiring maintainers to 
have gperf available might be reasonable if you could rework this to use a 
command line that will work with commonly-installed gperf versions.  Which 
version did you test with?
