[Buildroot] [git commit master 1/1] xz: fix build without wchar support

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=8296cf6c7ffa920ee9d37ac4695d52966fd1ecff
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

xz itself works without wchar support, but the C99 test in configure
fails when it isn't available. Fix it by providing a cached value for
the test.
