This disables compilation of this module on GNU/Hurd. Reported by Manolis Ragkousis <manolis837@gmail.com>. * m4/guix.m4 (GUIX_CHECK_LIBC_MOUNT): New variable. * configure.ac: Use it. Define 'BUILD_SYSCALLS_MODULE' conditional. * Makefile.am (MODULES, EXTRA_DIST): Make 'guix/build/syscalls.scm' conditional on BUILD_SYSCALLS_MODULE.
