[PATCH 2/2] maint: fix 'make syntax-check' findings

[Eric Blake]

Fix syntax check warnings that are unrelated to the new copyright
year.

* lib/local.mk (lib/autoscan/autoscan.list): Reduce indent, to
avoid mix of tab and 8 spaces.
* bin/local.mk (bin/autoconf.in): Likewise.
* lib/autoconf/c.m4 (_AC_CXX_CXX98_TEST_BODY): Use consistent case
in message.
