I got this while rebuilding GNAT GPL 2015; I think it's a change to the
behaviour of Apple's assembler in the latest command line tools.
The file I got the problem with was g-alleve.adb, part of the Altivec
extensions.
AdaCore are aware of the problem, and have a fix, but I don't know when
we will see it.
The Altivec extensions are probably of little interest unless you want
to be portable to Power computers (unlikely); so I disabled the
GNAT.Altivec tree by nulling out GNATRTL_ALTIVEC_OBJS in
gcc/ada/Makefile.rtl.
