This patch, based on proof of concept code from Richard adds code to
bitbake to allow individual tasks to optionally specify their stamp
file using the stamp-base flag. This takes the same form as the STAMP
variable but can be specified on a per task basis.
Code is also added to runqueue to ensure that if two tasks share the
same stamp file, only one will be executed at once.
A significant usecase for this code is to share source code (${S})
between recipes where separate build directories (${B}) are used.
