Subject: [PATCH] Don't use non-POSIX test

test "$test_CFLAGS" == "" &&         \

may cause an error on some POSIX shells and uses a style which is not
consistent with the other tests in configure.ac

Fixes https://bugs.freedesktop.org/show_bug.cgi?id=42588 and
https://bugs.gentoo.org/show_bug.cgi?id=387087
