Re: git: 902665210189 - main - libmagic: Remove support for older FreeBSD where xlocale was not available.

This breaks the cross building on linux.  The FREEBSD_XLOCALE_SUPPORT was
covering both the case of old FreeBSD as well as the case of building on
Linux/macOS. when we cross build, we define __FreeBSD_version to be 0.

All that really needs protecting is the xlocale.h include though. And
that's only needed on Linux / glibc, so the following patch should do the
trick:

 /* Define to 1 if you have the <xlocale.h> header file. */
+#ifndef linux /* Cross building tools build with glibc on linux */
 #define HAVE_XLOCALE_H 1
+#endif

Any objections to committing that? Or should I create a phab review to
discuss?
