[OPW,kernel,v2] Stop build recurse into not-compiled directories

Commit Message

Iulia Manda Jan. 7, 2015, 2:31 p.m. UTC

This patch stops the build from recursing into four directories (acpi, kprobes,
quota, vmw_vsock) where no file gets compiled in a tinyconfig build. This is
speeding up the compilation process.
