Bryan Hundven 6f8e89cb5c consistency: Use exported variables of required tools
We check for apps:

* make
* sed
* grep
* awk
* libtool/libtoolize
* install
* patch
* and more

...during configure. Our scripts should be consistent about using the
variables that define where the found tool was found.

Of course, we do hard-link these tools in buildtools, but that should be
a backup for the components we are building. Our scripts should always
use the tools we find.
