[bitbake-devel] [PATCH 4/5] [dora] bitbake: build.py: add single-quotes around already-expanded directory name

[Robert Yang]

From: Peter Seebach <peter.seebach at windriver.com>

If the computed name of a directory contains an undefined variable
reference, bitbake dutifully creates a directory with a name that has
${...} in it. However, the actual task script created then tries to cd
to that directory, and the cd command fails, because no such directory
exists -- because the shell has helpfully removed the ${...} which did
not match any actual variables.

Since we want the name to be used exactly-as-is, add single quotes around
the name so this doesn't cause strange failures running tasks, which
allows us to progress past such failures and get to a point where they
can be diagnosed.

(Bitbake master rev: 2809c2e6f2f35f9b08058950be896947ab5a0284)
