Bug#513564: glibc: Please redefine __i686 to work-around the infamous i686 compilation fail

[Yoram bar haim <bhyoram@zahav.net.il>]

Package: glibc
Version: 2.7-18
Severity: grave
Justification: renders package unusable

When compiling with gcc that uses march=i686 (or any sub-arch) gcc defines
__i686 to be 1, that causes instructions such as 
..ifndef __i686.get_pc_thunk.reg;
to fail as syntax error (because the prefix is 1).
if you force it to be redefid as __i686 it works fine
