The SRPM package created by 'make srcrpm-pkg' may not work
if rpmbuild is executed in a different machine.



%{make} %{makeflags} INSTALL_MOD_PATH=%{buildroot}
KERNEL_MODULE_DIRECTORY=%{KERNEL_MODULE_DIRECTORY} modules_install


will align with the specified install destination,
but depmod will still fail.
(same issue as 1/2)
