    gnu: fontforge: Support build on the Hurd.
    
    * gnu/packages/patches/fontforge-hurd.patch: New file.
    * gnu/local.mk (dist_patch_DATA): Add it.
    * gnu/packages/fontutils.scm (fontforge)[arguments]: When building natively 
on
    the Hurd, add new phase 'apply-hurd-patch' and use it, and replace phase
    'check' to skip two tests.

+Subject: [PATCH] Undefine "extended" macro temporarily on GNU Hurd
+
+GNU Mach microkernel header files (gnumach-dev 1.8+git20201129) added to
+struct i386_xfp_save in /usr/include/i386-gnu/include/mach/i386/fp_reg.h
+a new "extended" field which happens to collide with the macro definition
+"#define extended double" in FontForge, leading to FTBFS on GNU Hurd.
+
+This issue may be circumvented by temporarily undefining the "extended"
+macro before loading `<gio/gio.h>` and friends, and redefining the
+"extended" macro right after.
