Subject: Fuzz is fatal.  Update indentation in patch.

Apparently, some indentation changed between versions 4.7.2 and 4.7.3 of GCC.

BusyBox patch "does not use the location information, but instead treats a hunk
as a sort of regex" (BusyBox 1.21.0 editors/patch.c:209).  It ignores line
numbers and relies on context matching to find hunks to patch.  Therefore,
changes to the context in the original file cause BusyBox patch to fail to apply
a hunk.  Fuzz is fatal.

A patch needs to be refreshed when a new upstream version modifies its context.

    Hunk 2 FAILED 3688/3690.

         }
