guix/gnu/packages/patches/perl-no-build-time.patch
Ludovic Courtès 4187fe750f gnu: perl: Build deterministically, and make byproducts deterministic.
With this, a --rounds=2 build passes, and timestamps in POD files can be
controlled with 'SOURCE_DATE_EPOCH'.

* gnu/packages/patches/perl-deterministic-ordering.patch,
gnu/packages/patches/perl-no-build-time.patch,
gnu/packages/patches/perl-source-date-epoch.patch: New files.
* gnu/packages/perl.scm (perl)[source]: Use them.
* gnu-system.am (dist_patch_DATA): Add them.

Do not record the configuration and build time so that builds can be
