crosstool-ng/packages/glibc/2.30/0001-Add-ARC-architecture.patch
Alexey Neyman 86c2982568 Run patches thru manage-packages -P 
This refreshes the line numbers, removes any fuzz (which would make any
future forward ports easier) and standardizes the patch/file headers
(which makes them easier to read).
