[Qemu-devel] [PATCH v2] optionroms: Silence intermediate file removal

[Jan Kiszka <jan.kiszka@siemens.com>]

The build process of optionroms spits out an "rm ..." line. Moreover, it
removes all .o files that can be handy for debugging purposes.

Disable automatic intermediate removal and only clean up the unneeded
and large .img and .raw files.

Changes in v2:
 - comment on .SECONDARY purpose
 - make rm -rf dependent on success of build command
