[oe] error message on missing patchfile

[Frans Meulenbroeks]

Hi,

By accident I misplaced a patch file and I noticed that the build
process does not give an error for it during distribute_sources, but
only in do_patch.
It sems to me that the error should be given when distributing the sources.

I've checked in the logs and it says:
run.SRC_DISTRIBUTECOMMAND.4388:    ln -sf
"/home/frans/oe/openembedded/recipes/urjtag/urjtag-0.10/m4.patch"

This ln succeeds even if the file is not there.

I've tried to fix this and generate an error but apparenty my
knowledge of the build machinery is not enough.
Below is the patch that I produced.
The problem is that I get an error message saying unexpeced '(' on the line:
!         raise bb.build.FuncFailed("File does not exist: %s" % ${SRC})
Anyone a suggestion on what is wrong?
