wget: bump to 1.15. Fixes compilation in buildhost with new perl (bugs 15563 and 15718)

Compiling wget 1.14 in buildhosts with new perl (& texinfo?) versions may fail.
I experienced this with Ubuntu 14.04 x64 (with perl 5.18).
Bugs about this:

https://dev.openwrt.org/ticket/15563

The problem has been fixed upstream in wget:
http://git.savannah.gnu.org/cgit/wget.git/commit/?id=9e8d899a356d95be34737488bb8fd59d4c6b3dbd

http://git.savannah.gnu.org/cgit/wget.git/commit/doc?id=7f43748544f26008d0dd337704f02a6ed3200aaf

Both fixes are included in the already released wget 1.15.
Compiling that succeeds without any need to patch wget source.

I have compiled ax71xx for WNDR3700 and it compiled ok and works.
