Thanks for the review Denys, Apologies for multiple replies was facing some issues with relply all in mail.

Moving V=1 into EXTRA_OEMAKE is fine, but we can't remove the do_compile() override. . This is insufficient for jailhouse, which requires building:
1. Kernel modules (driver/jailhouse.ko)
2. Hypervisor binary (hypervisor/jailhouse.bin)
3. Userspace tools (tools/jailhouse, jailhouse-*)
4. Inmate demos (inmates/demos/*) — causing the install failure for all the demos during the build.

The do_compile() override is needed to run a plain oe_runmake which hits jailhouse's top-level Makefile and builds the full project.

If necessary I can send an V3 by moving V=1 into EXTRA_OEMAKE, but that doesn't serve our purpose of completely overriding the do_compile
And also I couldn't find an existing bbclass that does "run the top-level Makefile and build everything."
