Rather than expecting a pointer, the version of 'mount' in
guile-static-stripped now takes a string for the 'options' argument, just like
the 'mount' procedure in (guix build syscalls).
* gnu/packages/patches/guile-linux-syscalls.patch (mount): Expect a string or
#f for 'options' argument.
* gnu/build/file-systems.scm (mount-file-system): Use new 'mount' interface.
* gnu/packages/patches/guile-linux-syscalls.patch (scm_load_linux_module):
Leave 'errno' unchanged when ERR != 0.
* gnu/build/linux-modules.scm (load-linux-module*): Check for the errno
value of ARGS to determine whether the module was already loaded.
* gnu/packages/make-bootstrap.scm (%guile-static): Add
`guile-linux-syscalls.patch' as an input, and use it.
* gnu/packages/patches/guile-linux-syscalls.patch: New file.
* Makefile.am (dist_patch_DATA): Add it.
