Detecting host OS in Gnu make
Is this possible? Right now I'm developing some code for Linux, Windows and OS X. To build on each of the systems I've currently got separate build targets for each platform. Ideally I'd like to set up a single make rule that can detect the appropriate target and build it.
I know this is correctly done via autoconf for distribution but that is overkill for my purposes.

config.guess
CONFIG.GUESS(1) User Commands CONFIG.GUESS(1)
NAME
config.guess - guess the build system triplet
SYNOPSIS
config.guess [OPTION]
DESCRIPTION
The GNU build system distinguishes three types of machines, the `build' machine on which the compilers are run, the `host' machine on which
the package being built will run, and, exclusively when you build a compiler, assembler etc., the `target' machine, for which the compiler
being built will produce code.
This script will guess the type of the `build' machine.
Output the configuration name of the system `config.guess' is run on.
Operation modes:
-h, --help
print this help, then exit
-t, --time-stamp
print date of last modification, then exit
-v, --version
print version number, then exit
ENVIRONMENT VARIABLES
config.guess might need to compile and run C code, hence it needs a compiler for the `build' machine: use the environment variable
`CC_FOR_BUILD' to specify the compiler for the build machine. If `CC_FOR_BUILD' is not specified, `CC' will be used. Be sure to specify
`CC_FOR_BUILD' is `CC' is a cross-compiler to the `host' machine.
CC_FOR_BUILD a native C compiler, defaults to `cc'
CC a native C compiler, the previous variable is preferred
