Simple deleting the problematic wrap phase seems a good enough solution,
done in commit 154d270012.

I've also taken the opportunity to upgrade the package to version 0.56.2
and fixed a small usability issue (it would require the user to have
'cc' on their PATH).

Enjoy,

the bin/vala-0.54 shell script executes bin/valac-0.54 which executes bin/.valac-0.54-real.
it should execute bin/.vala-0.54-real instead.

expected (was the case before guix's update):
$ vala hello.vala
Hello, World!
$ ls
hello.vala

actual:
$ vala hello.vala
$ ls 
hello hello.vala
$ ./hello
Hello, World!
