Come to think of it, since Ada already requires GNU make, you ought to
be able to write
nmake.adb% nmake.ads%: sinfo.ads nmake.adt xnmake.adb
-$(MKDIR) bldtools
$(CP) $^ bldtools
(cd bldtools && gnatmake -q xnmake \
&& ./xnmake -b ../nmake.adb \
&& ./xnmake -s ../nmake.ads)
which invokes an obscure feature of pattern rules to inform make that
one command builds both targets at once. (This from memory, and I may
have the notation slightly wrong.)
