Share makefile rules and vars between client/server Move all make variables and rules duplicated between gkrellm and gkrellmd makefiles into a common file that can be included. This avoids duplication and hopefully avoids the two makefiles getting out of sync too much. This is also a preparation to ease overriding toolchain binaries (compiler, linker, pkgconfig) as part of windows cross compiling. This change also puts the "ar" tool into a variable that can be overridden if needed. Please note that this change uses the GNU Make specific include statement but AFAICS the makefiles already depend on GNU extensions in other areas (":=" and "ifdef" are non-standard make syntax).

# makefile variables and rules shared by both gkrellm and gkrellmd
Support mxe build environment for windows cross builds Override all tools with prefixed versions if the CROSS variable has been set. This is the recommended way to enable cross compilation using mxe without touching lots of environment variables first.

Use same cc/pkg-config in make and configure - Export the CC and PKG_CONFIG variables before calling configure scripts, especially for cross compilation and modified environments, otherwise configure might detect libraries that are not usable by the compiler later on - Replace the hardcoded pkg-config calls in configure with a variable that may be overridden by Makefile

# Make configure use identical environment
