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

[Allan McRae via arch-dev-public]

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
