PATCHES : make it not fail when reconfiguring

[Arniiiii]

When there's PATCHES, if we reconfigure, it will fail with next logs:

-- Configuring incomplete, errors occurred!

This can be solved just by adding the -N aka --forward to flags for patch command. patch --help for details.

wait a little bit, there's a strange problem with /usr/bin/patch: **** strip count ' 1 ' is not a number

[Arniiiii]

seems to be fixed

yes to /usr/bin/patch: **** strip count ' 1 ' is not a number , no to original issue

[Arniiiii]

solved by additionally specifying that it's normal patch?

[Arniiiii]

That's really interesting that it fails examples

I've found that without -n it doesn't fail if specified "-DCPM_SOURCE_CACHE=~/.cache/cpm" , but fails when it's not specified. That's really strange

[Arniiiii]

after some testing with options:
--forward + --rejectfile=- indeed works, but gives error code 1
--batch indeed works
