[dpdk-dev,v5] mk: add sensible default target with defconfig
Checks
Commit Message
Users can now use 'make defconfig' to generate a configuration using
the most appropriate defaults for the current machine.
<arch-machine-execenv-toolchain>
arch taken from uname -m
machine defaults to native
execenv is taken from uname, Linux=linuxapp, otherwise bsdapp
toolchain is taken from $CC -v to see which compiler to use

Nice :)

Excuse me for being pedantic with Makefile, I will avoid shell invocation:
+ @echo "Configuration done using" \
+ $(patsubst defconfig_%,%,$(notdir $(RTE_CONFIG_TEMPLATE)))
Applied with my pedantic change, thanks :)

Build commands
config get configuration from target template (T=)
+ defconfig auto-select target template based on arch, OS, etc.
all same as build (default rule)
build build in a configured directory
clean remove files but keep configuration
