I just checked a glibc 2.14, it has:
objdump --dynamic-syms /lib64/libc.so.6 |grep errlist
00000000003875e0 g    DO .data.rel.ro	0000000000000028  GLIBC_2.2.5 
h_errlist
00000000003869c0 g    DO .data.rel.ro	00000000000003e8 (GLIBC_2.2.5) 
sys_errlist
00000000003869c0 g    DO .data.rel.ro	00000000000003f0 (GLIBC_2.3) 
sys_errlist
00000000003869c0 g    DO .data.rel.ro	0000000000000438  GLIBC_2.12 
sys_errlist
00000000003869c0 g    DO .data.rel.ro	0000000000000420 (GLIBC_2.4) 
sys_errlist
00000000003869c0 g    DO .data.rel.ro	00000000000003f0 (GLIBC_2.3) 
_sys_errlist
00000000003869c0 g    DO .data.rel.ro	00000000000003e8 (GLIBC_2.2.5) 
_sys_errlist
00000000003869c0 g    DO .data.rel.ro	0000000000000438  GLIBC_2.12 
_sys_errlist
00000000003869c0 g    DO .data.rel.ro	0000000000000420 (GLIBC_2.4) 
_sys_errlist

So, 0x438 is the correct value and thus check-abi is fine.
