# Commands can be overwritten on the command line with "make <VAR>=<VALUE>":
#
# $ make CC=gcc-4.8
#
# The "cmd_define" macro wraps the command definition so that the commands
# can be user supplied and are still pretty-printed for the build process.
#
# The macro is called with the following parameters:
#
# $(1) - Used command variable in the Makefiles
# $(2) - Pretty Print output for the command
# $(3) - Default command if not user-specified
#
# The Example below...

#
# CC = $(CROSS_COMPILE)gcc
# CC_SILENT := $(CC)
# override CC = $(call echocmd," CC ",/$@)$(CC_SILENT)
#
# The "strip" make function is used for the first parameter to allow blanks,
# which improves readability.

# INSTALLDIR: Finally install s390-tools to INSTALLDIR. This can be used

# used for building s390-tools e.g. with rpmbuild.

# The difference between INSTALLDIR and DESTDIR is that for INSTALLDIR
# internally used directories (e.g. for config files) are adjusted.

#
# $ cd cpumf
