# For cross-builds to work, UNAME_M has to map to ARCH and arch specific
# directories and targets in this Makefile. "uname -m" doesn't map to
# arch specific sub-directory names.

# UNAME_M variable to used to run the compiles pointing to the right arch
# directories and build the right targets for these supported architectures.
#
# TEST_GEN_PROGS and LIBKVM are set using UNAME_M variable.
# LINUX_TOOL_ARCH_INCLUDE is set using ARCH variable.
#
# x86_64 targets are named to include x86_64 as a suffix and directories
# for includes are in x86_64 sub-directory. s390x and aarch64 follow the

# s390x and aarch64.
