The xconfig Kconfig target requires a C++ compiler because it uses Qt.

Due to the fact that on ARM headers types are substituted to uint64_t and
then uint64_t is also substituted to contain the aligment, this would lead
to some types containing two __align8__ directives. Fix this by first
expanding Xen specific types to uint64_t only, and then replacing all the
uint64_t types to __align8__ uint64_t. This relies on the fact that all
Xen-specific types will have longer names, so they will always be replaced
first.

The current seedery doesn't work with BSD sed, so remove the try to match
int64_t also (since there's none at the moment). Also, apply the same
treatment to all arch headers, currently this is only done to x86_64
headers.

Ian, this is a backport candidate.
Note that the code still functions without this fix because the third
parameter to xc_dom_register_external is only for accounting purpose.

The xc_psr_* functions expect the type to be xc_psr_cat_type instead of
libxl_psr_cbm_type, so do the conversion.

By explicitly casting it to unsigned.
Reasoning on why this is needed, provided by Andrew Cooper:
"Ocaml stores integers shifted left by one, and with the bottom bit set.
Values with the bottom bit clear are pointers into the GC'd heap. Values
with the bottom bit set are integers, and need to be shifted by 1 bit to
have calculations performed."

It is incorrect to add the LDFLAGS to the CFLAGS, and some compilers will
error out if linker flags are passed when creating object files. Fix this by
properly passing CFLAGS and LDFLAGS, instead of putting everything in
CFLAGS.
