[arch-dev-public] Moving base-devel dependencies to [core]

Hi all, I notice when using devtools, the following packages from [extra] get pulled into our clean build root: extra/gc extra/guile extra/libcroco extra/libsysprof-capture extra/libxml2 These are all dependencies of base-devel packages. I'd like to move them to [core] so they are captured by the signoff process. Thank you for your lack of objection. :) Allan
