Description:

Platform: slackware64-current, php-5.6.8/9

The phar symlink in the binary directory point to a non-existing file in the build folder

$ ls -la /usr/bin/phar
lrwxrwxrwx 1 root root 35 mag 8 20:50 /usr/bin/phar -> /tmp/package-php//usr/bin/phar.phar

but there's nothing in /tmp/package-php//usr/bin/phar.phar (the link is broken) and the invocation of phar from the command line fails

$ ls -la /tmp/package-php//usr/bin/phar.phar
/bin/ls: cannot access /tmp/package-php//usr/bin/phar.phar: No such file or directory

$ ls -la /usr/bin/phar.phar
-rwxr-xr-x 1 root root 14823 apr 24 20:32 /usr/bin/phar.phar

the problem seems to be a line in the file ext/phar/Makefile.frag where the link is created with the following command

$(LN_S) -f $(INSTALL_ROOT)$(bindir)/phar.phar $(INSTALL_ROOT)$(bindir)/phar

we better omit the path and make the symlink relative (see also the discussion in https://github.com/php/php-src/pull/1288)

the patch is a pull request on github: https://github.com/php/php-src/pull/1294

Test script:
---------------
$ phar
-bash: phar: command not found
$

Expected result:
----------------
$ phar
No command given, check /usr/bin/phar help
$
