xen: pass compiler flags via Xen-provided variables
Fix the method of passing compiler flags into the Xen build, which is
needed to fix compilation of hvmloader, a 32-bit firmware binary that is
required for Xen to be able to run HVM-mode guest VMs. It must not be
compiled with SSE compiler options enabled, so the Xen build clears
CFLAGS, which is a problem with _FORTIFY_SOURCE present in CC because
it must be paired with a compiler optimization flag that was in CFLAGS.
This change fixes the compilation failure that stated
"_FORTIFY_SOURCE requires compiling with optimization (-O)".
32-bit ARM needs the TUNE_CCARGS to be retained as passed via CC
to ensure that configure is able to generate binaries for the
correct ABI, so is handled as a separate case.
