3# Inputs:
4#	combo_target -- prefix for final variables (HOST_ or TARGET_)
5#
6# Outputs:
7#   $(combo_target)OS -- standard name for this host (LINUX, DARWIN, etc.)
8#   $(combo_target)ARCH -- standard name for process architecture (powerpc, x86, etc.)
9#   $(combo_target)GLOBAL_CFLAGS -- C compiler flags to use for everything
10#   $(combo_target)DEBUG_CFLAGS -- additional C compiler flags for debug builds
11#   $(combo_target)RELEASE_CFLAGS -- additional C compiler flags for release builds
12#   $(combo_target)GLOBAL_ARFLAGS -- flags to use for static linking everything
13#   $(combo_target)SHLIB_SUFFIX -- suffix of shared libraries
