[OE-core] [morty][PATCH v2] perl, do_install_ptest_base: add "--" into "tar" command line

[Ivan Efimov]

Add explicit separator "--" between options and arguments in "tar"
command to avoid mistakenly detection file with name starts with "-" as
an unknown option

Steps for reproduce issue:

* Add next variables into "conf/local.conf":

  CC_append_pn-perl = " -MD -Ml,M"
  CXX_append_pn-perl = " -MD -Ml,M"

* Then "bitbake perl"
* Task "do_install_ptest_base" will fail with error:

    tar: invalid option -- '.'

  because of presence next file

    tmp/work/i586-poky-linux/perl/5.22.1-r0/perl-5.22.1/-.d

  which starts from minus (-) sign and Yocto tries to run:

    tar <options> -.d <other files>

  and "tar" parse "-.d" as a option instead of file

Upstream-Status: Pending
