The user can now create a custom local override file to override the
source directory for various packages.
An example override file:
ZLIB_OVERRIDE_SRCDIR = /tmp/zlib
STRACE_OVERRIDE_SRCDIR = /opt/strace-4.5.20
would tell Buildroot to use the zlib and strace source code from the
specified directories, instead of download, extracting and patching
the code has done usually by Buildroot.

+ A package override file is a short makefile that contains
+ variable definitions of the form <pkg>_OVERRIDE_SRCDIR,
+ which allows to tell Buildroot to use an existing directory
+ as the source directory for a particular package. See the
+ Buildroot documentation for more details on this feature.
