[oe] patch 2.6 rejects relative paths

[Elena Vengerova]

Hello,

I have patch 2.6.1 on my Fedora.
I've found out that it rejects patches like 
recipes/tcltk/tcl-8.5.8/mips-tclstrtod.patch with relative paths:

--- ../generic/tclStrToD.c.orig
+++ ../generic/tclStrToD.c

I failed to find the reason, but my colleague said me (she was unsure) 
that it was security hole fix.
Thus looks like it's no way to force patch behave like old one.

I wonder if some work around is possible (except patch downgrade) or 
it's necessary to fix the recipes.

Thanks,
     Helen
