Following compiler warning:

/home/fornwall/termux/mc/src/lib/vfs/interface.c: In function 'mc_open':
/home/fornwall/termux/mc/src/lib/vfs/interface.c:203:28: warning: 'mode_t' is promoted to 'int' when passed through '...'
         mode = va_arg (ap, mode_t);
	                    ^
/home/fornwall/termux/mc/src/lib/vfs/interface.c:203:28: note: (so you should pass 'int' not 'mode_t' to 'va_arg')
/home/fornwall/termux/mc/src/lib/vfs/interface.c:203:28: note: if this code is reached, the program will abort

which causes crash on arm devices due to mode_t being unsigned int.
