When gnatmake has been invoked with -gnatc for a spec, if invoked later also
with -gnatct for the body, will not attempt compilation. This patch ensures
that the body is compiled.
The test for this is to invoke gnatmake -gnatc on a spec, then on the
corresponding body. In both cases the compiler should be invoked.

Tested on x86_64-pc-linux-gnu, committed on trunk

	* make.adb (Check): When compiling with -gnatc, recompile if the ALI
	file has not been generated for the current source, for example if it
	has been generated for the spec, but we are compiling the body.
