[elpa] externals/org eb6cabdee5: mk: Expand shell commands once only

[ELPA Syncer]

branch: externals/org
commit eb6cabdee591a18e6885998917ae767043610391
Author: Ihor Radchenko <yantar92@posteo.net>
Commit: Ihor Radchenko <yantar92@posteo.net>

    mk: Expand shell commands once only
    
    * mk/targets.mk (GITVERSION):
    (GITSTATUS):
    (DATE):
    (YEAR): Only expand the variables once, not in every make sub-process.
    Previous code ran pwd/date/git in every make sub-process, slowing
    things down significantly and unnecessarily.
