Hello folks,
The latest kvm-unit-test will fail to build on i386 systems, with the
error message:
gcc -m32 -O1 -g -MMD -MF lib/x86/.usermode.d -Wall

make: *** [lib/x86/usermode.o] Error 1
A bisect shows the cause is the newly added usermode.c in commit
1c93387eecbe, just like the compiler complained here.
