[bug#66889] [PATCH 0/2] Unbundle igraph dependencies.

[David Elsing]

These patches unbundle everything from igraph and update it to 0.10.7.
As newer SuiteSparse versions always use an integer width of 64, I set
the same in igraph. Would it be better to create a package variant of
suitesparse-cxsparse for igraph with an integer width depending on the
architecture? Upstream doesn't recommend unbundling CXSparse for that
reason.

David Elsing (2):
  gnu: Add pcg-c.
  gnu: igraph: Update to 0.10.7.
