Subject: scripts: allow tuning any test build option
X-Git-Tag: spdx-start~7036
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=d568d5d38d8bbacb43b67a21a39a16df0855774a;p=dpdk.git

scripts: allow tuning any test build option

Any build option can be enabled or disabled by appending the end
of its name to the config name.
Examples:
	+INTRINSICS to enable CONFIG_RTE_FORCE_INTRINSICS
	~RXTX_CALLBACKS to disable CONFIG_RTE_ETHDEV_RXTX_CALLBACKS

These builtin (lowercase) options are also added for convenience:
	+debug to enable every debug options
	+default to set target machine as default
