07e5555a8f modprobe-small: (un)load all modules which match the alias, not only first one 
Closes 627 and 7034.

Commonly seen case is (un)loading of an alias
which matches ata_generic and a more specific ata module.

For example:

modprobe [-r] pci:v00008086d00007010sv00000000sd00000000bc01sc01i80
(ata_generic and pata_acpi)

modprobe [-r] pci:v00001106d00000571sv00001509sd00009022bc01sc01i8a
(ata_generic and pata_via)

7537406edd build system: specify '-nostldlib' when linking to .o files 
For certain cross build scenarios the LD variable is overridden
to use the gcc executive to ensure all the target tuning parameters
are used.  In these cases, the executive errors out as shown below
but since this step is only linking to a .o file the standard libs
are not needed.

    $ make LD=gcc applets/built-in.o
      LD      applets/built-in.o
    /usr/bin/ld: cannot find -lgcc_s
    /usr/bin/ld: cannot find -lgcc_s
    collect2: ld returned 1 exit status
    make[1]: *** [applets/built-in.o] Error 1
    make: *** [applets_dir] Error 2

a3f326cd66 swapon/swapoff: size reduction, cleanup, fixes, improvements 
1) real swapon/swapoff handles also devices on the commandline with -a;
2) xstat(device)  in  swap_enable_disable aborts on error when cycling through
   fstab so some devices  are not handled;
3) duplicated code for ENABLE_FEATURE_SWAPON_DISCARD and
   ENABLE_FEATURE_SWAPON_PRI was moved to functions.
4) silence some error messages with -a;
5) minor cleanups and code refactoring reduced the size as per bloat-check:
6) I also added support for /proc/swaps handling to swapoff:
"When the -a flag is given, swapping is disabled on all known  swap  devices
 and  files  (as  found  in  /proc/swaps  or /etc/fstab)."
So now swapoff first cycles through  /proc/swaps and then through fstab
to swapoff all devices.
