Apparently gwrap will not compile with guile-2.2 [1], even though the
news for version 1.9.15 says it "allows" Guile 2.2 [2]:
> it will _not_ compile using 2.2
Furthermore, it seems like it isn't being developed anymore either [1]:

Also, guile-gnome-2.16.5 is apparently compatible with guile-2.2 [3],
but I'm not sure how they built it with guile-2.2 because gwrap 1.9.15
(latest release) apparently doesn't build with guile-2.2. (And certainly
when I try to build gwrap 1.9.15 with guile-2.2 it doesn't work. Maybe
it can be made to work with certain compile flags, but I haven't pursued
that further due to [1] anyway.) This is why guile-gnome is still on
2.16.4 here. Because, although 2.16.5 can still (apparently) build with
guile-2.0.14, guile_2_0 is only at guile-2.0.13.
So to update guile-gnome to 2.16.5, guile_2_0 would first have to be
updated to 2.0.14.

The build provides as text a summary of the build, including the
absolute path of the compiler used for compilation. Unfortunately, this
pulls in stdenv.cc as a transitive closure.
So this change just calls remove-references-to as a postInstall step for
the one stdenv.cc dependency.
See #29889 for details.
