    security/heimdal: fix with stock clang >= 16
    
    Upstream clang >= 16 made -Wimplicit-function-declaration into an error
    by default. In the base system, this change was reverted to reduce the
    fallout in ports, because there are many problematic configure scripts.
    
    For security/heimdal this also applies, so for building the port with
    devel/llvm16 or higher we need to add -Wno-implicit-function-declaration
    to CFLAGS.
    
    While here, use LDFLAGS+= for -Wl,--undefined-version, to avoid
    overwriting any user-specified LDFLAGS.
