Build fails without GNU make

[eserte]

On systems where the default make is not GNU make, e.g. on FreeBSD systems, the build step fails. On older FreeBSD systems:

Output from '/usr/bin/make':

make: "/home/cpansand/.cpan/build/2023092409/App-Sandy-0.25-vurlG2/Makefile" line 1560: Need an operator
make: "/home/cpansand/.cpan/build/2023092409/App-Sandy-0.25-vurlG2/Makefile" line 1573: Need an operator
make: Fatal errors encountered -- cannot continue
make: stopped in /home/cpansand/.cpan/build/2023092409/App-Sandy-0.25-vurlG2

or with newer FreeBSD:

Output from '/usr/bin/make':
