Hello,
This bug follows #763043, with some updates.
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=763043
Summary: Firstly, the byte7 should be 0xfc to correctly match both
ELF_OSABI=0 and ELF_OSABI=3. In addition, this affects not only x86_64,
but some other ports, too.
I only tried powerpc, and here is an example:
$ file /usr/lib/gcc/powerpc-linux-gnu/4.9/cc1
/usr/lib/gcc/powerpc-linux-gnu/4.9/cc1: ELF 32-bit MSB executable, PowerPC or
cisco 4500, version 1 (GNU/Linux), dynamically linked, interpreter
/lib/ld.so.1, for GNU/Linux 2.6.32,
BuildID[sha1]=af334aed1745fa3623a18e6fcf6826d029e77657, stripped
$ hd /usr/lib/gcc/powerpc-linux-gnu/4.9/cc1|head -1
00000000 7f 45 4c 46 01 02 01 03 00 00 00 00 00 00 00 00 |.ELF............|

Yixuan
