    tools/build/Makefile: Always add md4.h to SYSINCS
    
    Since libmd was added to the bootstrap, building main on stable/14
    fails because of an incompatibility in its old md4.h.  Fix this by
    always including md4.h in the bootstrap headers, instead of only
    doing so when building on a non-FreeBSD host.
    
    Fixes:          50de0bf50512 ("flua: Always build as a bootstrap tool")
