Hi!

On git master, building and running 'make check' on sparc64 fails with:

Built and tested with:

$ mkdir build
$ cd build
$ export CFLAGS='-pipe -O2 -g -mcpu=ultrasparc'
$ ../configure --prefix=/usr
$ make
$ make check

Tested on Debian/sparc64, kernel 4.5.1. The same issue can be observed on the
buildds where glibc fails to build as well [1].

Cheers,
Adrian
