--- Comment #2 from Chantry Xavier <shiningxc@gmail.com> ---
If I build with -Wl,-x , valgrind works fine on the resulting binary.

Binary linked with -Wl,-x :
% readelf -Ws ./a.out | grep test
    20: 0000000000400568    11 IFUNC   GLOBAL DEFAULT   14 test

Binary linked with default ldflags :
% readelf -Ws ./a.out | grep test 
    11: 0000000000400544    36 FUNC    LOCAL  DEFAULT   14 mytest
    12: 0000000000400568    11 FUNC    LOCAL  DEFAULT   14 resolve_test
    37: 0000000000400568    11 IFUNC   GLOBAL DEFAULT   14 test

Versions used:
valgrind-3.7.0
gcc (Debian 4.6.3-1) 4.6.3 
GNU gold (GNU Binutils for Debian 2.22) 1.11
