This is http://gcc.gnu.org/PR53468

As mentioned in /usr/share/doc/libc6/NEWS.Debian.gz, using

	LIBRARY_PATH=/usr/lib/$(gcc -print-multiarch)
	CPATH=/usr/include/$(gcc -print-multiarch)
	export LIBRARY_PATH CPATH

before the usual

	./configure <configure args>
	make

is supposed to work around it.  Does it work for you?

Curious,
Jonathan
