[Buildroot] [PATCH 1/2] package: pkg-generic: Support building override source without copying in common package infrastructure.

[Sonic Zhang]

From: Sonic Zhang <sonic.zhang at analog.com>

1) Set _SRCDIR a different path from _DIR if _OVERRIDE_SRCDIR is
defined. Generic package's make rules should replace $@ by $(_SRCDIR).
2) Set object path to _MAKE_FLAGS if _OVERRIDE_SRCDIR is defined.
Generic package's make rules should forward _MAKE_FLAGS to the make
command.
3) Remove unused makefile target .stamp_rsynced and .stamp_rsync_sourced.
4) Add .stamp_patch target to patch the external source tree
if _OVERRIDE_SRCDIR is defined.
