[FYI] {master} build: clearer diagnostic if "make" is invoked before "./configure" |

Since a GNUmakefile wrapper has been introduced in our build
system, a "make" invocation issued before a "./configure" one
has caused GNU make to die with the cryptic message:
GNUmakefile:18: Makefile: No such file or directory
GNUmakefile:19: /syntax-checks.mk: No such file or directory
make: *** No rule to make target `/syntax-checks.mk'. Stop.
* GNUmakefile: Detect when we are being run from an unconfigured
tree, and give helpful diagnostic.
