[gentoo-science] [PATCH 2/2] virtual/{c,}blas: add sci-libs/blis as a candidate.

[heroxbd@gentoo.org]

From: Benda Xu <heroxbd@gentoo.org>

  On ld.so-based systems, runtime library switching is possible.  We
  use 'eselect-ldso' to flag this possibility.  In this case, blis can
  used as a drop-in replacement via an `eselect` call.

  Otherwise If USE eselect-ldso is not set, only reference
  implementation will be pulled in.

Package-Manager: Portage-2.3.52, Repoman-2.3.12
Signed-off-by: Benda Xu <heroxbd@gentoo.org>
