This patch makes the build-system integration of noux packages usable for non-Noux targets. It moves the GNU build system wrapper to ports/mk/gnu_build.mk, which is now included by noux.mk. This way, non-noux applications can use the same build-system wrapper. So the porting of individual applications becomes easier. This change removes the 'NOUX_' prefix use the various build variables used by the noux-pkg's target.mk files to steer the behaviour of the GNU build system. E.g., NOUX_CONFIGURE_ARGS is now called CONFIGURE_ARGS. Note that there is a single exception to this pattern: The formerly named NOUX_LIBS is now called LDLIBS because the plain LIBS variable is used by the Genode build system. Fixes #2094
