[oe] Rebuild from packaged staging: issues with do_package_update_index_ipk

[Andrea Adami]

I'm testing rebuild from packaged staging (cleaning all in /tmp but
/pstage) and I was stopped by a new issue with package_ipk.bbclass:

+ ipkgarchs='all any noarch arm  armv4 armv4t armv5te c7x0'
+ '[' '!' -z '' ']'
+ touch /oe/build/tmp/deploy/glibc/ipk/Packages
touch: cannot touch `/oe/build/tmp/deploy/glibc/ipk/Packages': No such
file or directory

Basically if you remove the /ipk dir the script will fail...perhaps
adding a mkdir -p would help.

Any opinion?

Regards

Andrea
