mklibs: update to 0.1.34 (v2) SVN-Revision: 32165 2012-06-10 17:07:46 +00:00			`--- a/src/mklibs`

tools/mklibs: update to 0.1.44 and convert to Python 3 Since the switch to Python 3 build fails if CONFIG_USE_MKLIBS is set ("Strip unnecessary functions from libraries" in menuconfig) as mklibs hasn't been converted to run on Python 3. * update to most recent upstream version which brings some reproducibility fixes * converted to Python 3 using 2to3 * fixed mixed tab/spaces indentation * fixed use of string.* functions * some more minor fixes to make Python 3 happy Fixes commit 19938c8de7 ("build: switch to Python 3") Signed-off-by: Daniel Golle <daniel@makrotopia.org> 2019-07-26 21:45:47 +00:00			`@@ -616,7 +616,7 @@ while 1:`
