As described in the PR, this patch

	https://gcc.gnu.org/ml/gcc-patches/2015-08/msg01549.html

broke bootstrap on a couple of platforms that lack strndup in libc.
Fixed as follows, matching other uses of xstrndup in the gcc
subdirectory.

Bootstrapped on i386-pc-solaris2.10, installed on mainline as obvious.

	Rainer
