GIT-BUILD-OPTIONS defines PERL_PATH to be used in the test suite. Only a few tests already actually use this variable when perl is needed. The other test just call 'perl' and it might happen that the wrong perl interpreter is used. This becomes problematic on Windows, when the perl interpreter that is compiled and installed on the Windows system is used, because this perl interpreter might introduce some unexpected LF->CRLF conversions. This patch makes sure that $PERL_PATH is used everywhere in the test suite and that the correct perl interpreter is used.
