kvm-unit-tests fail to build with GCC10:
/usr/bin/ld: lib/libcflat.a(usermode.o):
./kvm-unit-tests/lib/x86/usermode.c:17: multiple definition of `jmpbuf';
lib/libcflat.a(fault_test.o):
./kvm-unit-tests/lib/x86/fault_test.c:3: first defined here
It seems that 'jmpbuf' doesn't need to be global in either of these files,
make it static in both.
