[PATCH] Wrap RUNTIME_PREFIX warning in a compile-time condition

From: Johannes Sixt <j6t@kdbg.org>

When RUNTIME_PREFIX is enabled, the installation prefix is derived by trying a limited set of known locations where the git executable can reside. If none of these is found, a warning is emitted.

When git is built in a directory that matches neither of these known names, the warning would always be emitted when the uninstalled executable is run. This is a problem on Windows, where gitk picks the uninstalled git when invoked on the build directory and gets confused by the warning.

With this patch, individual developers can disable the warning by setting
   BASIC_CFLAGS += -DNO_WARN_RUNTIME_PREFIX
in config.mak.
