Subject[PATCH 2/4] scripts/nsdeps: don't prepend $srctree if *.mod already contains full paths
Date
When building in-tree modules, the *.mod file contains relative paths.
When building external modules, the resulting *.mod file contains absolute
paths. Allow for the nsdeps script to account for both types of paths and
only prepend $srctree in the case of relative paths. Otherwise, the script
will append $srctree to the path regardless and it will error out with file
not found errors if the path was already absolute to begin with.

The sed regex is getting more ugly. It's not my strong point :/ If anyone
has a better regex to prepend $srctree for every relative path encountered
while ignoring absolute paths, I'm all ears.
