Subject: [PATCH] kbuild: use -Werror=implicit-... instead of -Werror-implicit-...

The flag '-Werror-implicit-function-declaration', present in GCC 2.95,
stopped to be documented in GCC 4.3, replaced by the more generic
'-Werror=...' form.

So, use the equivalent '-Werror=implicit-function-declaration' instead.
