gnu: perl: Hack the replacement perl to think it is version 5.26.1.
Fixes <https://bugs.gnu.org/31216>.
This is a followup to commits 217b8c2e061a5b637e198f1ed9960d4abe2b0a46,
44b98b00026e62766620dbc4330a305282d61069, and
35fbe194c3da264859a5addc661b9fbc2dc8ecc7.
Complications arise when grafting perl unless the version of the replacement
perl matches that of the original. So, here we add 'perl/fixed', which is
built from the perl-5.26.2 source but hacked to believe it is version
5.26.1.
* gnu/packages/perl.scm (perl)[replacement]: Use perl/fixed, not
perl-5.26.2.
(perl-5.26.2): Remove compatibility symlinks.
(perl/fixed): New variable.
