apt 0.7.14: do_compile failed with gcc 4.7

apt do_compile failed with gcc 4.7:

deb/deblistparser.cc: In member function 'virtual short unsigned int debListParser::VersionHash()':
deb/deblistparser.cc:212:13: error: redeclaration of 'char* I'
deb/deblistparser.cc:202:22: error: 'const char** I' previously declared here

Backport the patch from the upstream would fix the problem, both target and
native apt need it.

[YOCTO #2488]
