[kvm-unit-tests PATCH v2 3/4] riscv: Fix out-of-tree builds

[Andrew Jones <andrew.jones@linux.dev>]

My riscv compiler doesn't seem to want to create directories as other
compilers are apparently doing. There's only a few of them, so let's
just manually create them in configure. And riscv also needed
'-I lib' in CFLAGS.
