4Subject: [PATCH] Makefile: drop explicit undefine PYLIB for compatibility with
5 make 3.81
6
7GNU make 3.81 does not like the explicit tab-indented undefine:
8
9Makefile:41: *** commands commence before first target.  Stop.
10
11Dropping the indentation also doesn't work:
12
13Makefile:41: *** missing separator.  Stop.
14
15So simply drop the undefine logic.  As explained in the GNU make manual,
16undefine is not commonly needed as E.G. ifdef checks for a non-zero string:
