"make check" failure on Solaris 10 as File::Temp->newdir is missing

[Paul Eggert]

With GNU Make 4.3.91 on Solaris 10 sparc, 'make check' fails as shown at 
the end of this email.

Solaris 10 (supported by Oracle through January 2024) uses Perl 5.8.4. 
tests/README says Perl 5.004 or later is needed, so I guess either that 
README file needs to be updated to say a later Perl version is needed 
(not sure which version), or tests/test_driver.pl needs to be backported 
to Perl 5.8.4.

  make  check-local
  cd tests && perl  ./run_make_tests.pl -srcdir 
/var/run/rpc_door/eggert/make-4.3.91 -make ../make
  Can't locate object method "newdir" via package "File::Temp" at
