Centralize GNU utility checks in autoconf Tests for program presence, such as those formerly embedded in the top-level Makefile for gawk and gsed, are better suited for autoconf. Note that it is not sufficient to merely export AWK and SED environment variables, as packages may still directly invoke awk(1) and sed(1) with non-standard features independent of the autotools framework. Wrapper scripts therefore remain necessary, although these are now generated by the configure script to avoid hard-coded paths. Do not assume the existence of /bin/bash on all systems.

Add an "--enable-linux" option to ./configure I keep forgetting that the default option is to build newlib. This flag changes the default target to Linux, so I don't keep forgetting to type "make linux".
