[BusyBox] here's a working multicall for e2fsprogs-1.18 _with_ uClibc support for i386

[Manuel Novoa III]

Hello all,

Attached is a patch to the stock e2fsprogs-1.18 package and e2fsbox-0.01,
a simple multicall binary for the e2fsprogs.  Best of all, besides working
for gcc, it works with gcc-uClibc-i386. ;-)  Other archs currently need some
additional patching to e2fsprogs or some additional work on uClibc.

Standalone binary sizes for comparison appear at the end of this message.

Anyone wanting to run with this is welcome to, as I plan to continue
concentrating primarily on uClibc stuff.

Manuel
