[PATCH] scripts/kernel-doc: don't use uninitialized SRCTREE
Current kernel-doc (perl) script generates this warning: Use of uninitialized value in concatenation (.) or string at scripts/kernel-doc line 1668. So explicitly check for SRCTREE in the ENV before using it, and then if it is set, append a '/' to the end of it, otherwise the SRCTREE + filename can (will) be missing the intermediate '/'.
