The problem isn't the compiler, but the linker, so we ought to turn this
flag on for all ELF-based systems where we compile Qt with -Bsymbolic,
but so far only the Intel compiler has been affected. We can turn it on
as needed for other systems.
The cause of the problem is the way that ICC materializes the pointer-
to-member-function: it stores the full 2*sizeof(void*) data in an
anonymous variable, so that it can load it in one go, such as one 16-
byte SSE aligned load on 64-bit systems. That relocation in a data
variable gets turned into a fixed-position copy relocation by the
linker, which breaks the signal-identification mechanism.
GCC and Clang are likely to be affected if anyone did:
static const auto destroyed = &QObject::destroyed;
QObject::connect(obj, destroyed, [](){});
Task-number: QTBUG-52439
