Subject: [PATCH] common.mak: fix compiler command line for afl-clang
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`afl-clang` requires a white space between a option name and the option value.
Therefore let's fix this for `-xc` by adding a white space.

How to reproduce:

$ make -C zdump CC=afl-clang-fast LINK=afl-clang-fast
