populate_sdk_base.bbclass: Improve debugging capabilities for SDK installer
After having to debug the SDK installer a few times in
addition to the relocation code the following patch was created
to improve the capabilities around debugging the SDK installer.
1) Add a verbose mode -D which set a set -x to see what
the SDK installer is doing.
2) Add a mode -S to save the relocation scripts for the purpose
of debugging them in conjunction with -D
3) Add a mode -R to not execute the relocation scripts for the
purpose of debugging the relocations.
