If the 51 most significant bits of the SCCB address are zero or equal to

Also moved the check for privileged mode to sclp_service_call() to have

As a followup to commit 5f04c14a

So far, the DIAG 500 hypervisor call was only setting -EINVAL in
R2 when a guest tried to call this function with an illegal subcode.
This patch now changes the behavior so that a specification exception
is thrown instead, since this is the common behavior of other DIAG
functions (and other CPU instructions) when being called with illegal
parameters.

The SET-ARCHITECTURE handler in QEMU caused a program interruption.
This is wrong according to the "Principles of Operations" specification
(since SIGP should never cause a program interrupt) and was likely only
introduced for debugging purposes. Since we handle SET-ARCHITECTURE in
the kernel already and only dropped to user space in case of bad mode
parameters, we should just report INVALID PARAMETER in QEMU instead.

gmodule-2.0's pkg-config files include -Wl,--export-dynamic, which breaks
static builds.  It is a glib bug, but we need to support --static builds for
the linux-user targets, and in the end all that is needed to fix this is:

* outlaw --enable-modules --static, which makes little sense anyway

* only include gmodule-2.0's cflags and ldflags if --enable-modules is
specified on the command line.

Check that the C++ compiler works with the C compiler; if it
does not, then don't pass CXX to the build process. This
fixes a regression where QEMU was no longer building if the
build environment didn't have a C++ compiler (introduced
in commit 3144f78b, which incorrectly assumed that rules.mak
would only see a non-empty $(CXX) if configure had actually
found a working C++ compiler).
