when exec lcov in bash, the following error will appear:
/usr/bin/env: 'perl -w': No such file or directory
perl uses the -w option to enable many warnings. But the
env command can't pass the argument to perl, instead it
treate perl -w as a file. To fix this issue, just keep
the origin perl path and not use env command.
