external/pflash: Fix makefile dependencies
When building under buildroot, libflash was being built before the
links:
make[2]: *** No rule to make target 'libflash/libflash.c', needed by
'libflash-libflash.o'. Stop.
make[2]: *** Waiting for unfinished jobs....
LN ccan
LN common
LN libflash
To reproduce this outside of buildroot, set PFLASH_VERSION to anything.
This is another race that is only exposed in certain conditions. By
describing the dependencies on the source files the build works again.
I think it's almost time to stop using symlinks.
