Subject: [PATCH] config: fix "maybe-uninitialized" error when compiling with
 CFLAGS=-Og
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Using GCC 12.2.0 with the following build steps:

    CFLAGS=-Og meson bld
    ninja -C bld

...produces the compiler error:

    ../config.c:2000:18: error: ‘sym_equal’ may be used uninitialized
    [-Werror=maybe-uninitialized]

This commit fixes that by using BUG() to assert that all possible
values are accounted for in the offending switch statement.
