Reproducer (to be gnatchopped)

I’ve built GCC 5.1.0 for arm-eabi (over x86_64-apple-darwin13), and while
adding finalization to my RTS I got the following bug box while compiling
a-finali.ads. This doesn’t happen when compiling fully (fails, of course):

$ gprbuild -c -u -f -P build_runtime.gpr a-finali.adb
build_runtime.gpr:1:09: warning: there are no Asm_Cpp sources in this project
arm-eabi-gcc -c -gnatpgn -gnatqQ -nostdinc -ffunction-sections -fdata-sections
-g -Og a-finali.ads
cannot generate code for file a-finali.ads (package spec)
gprbuild: *** compilation phase failed

Good idea, will do. Just waiting for approval to commit.
