[Qemu-devel] [PATCH v3] 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. So
disable automatic intermediate removal.

Changes in v3:
 - do not remove intermediate file manually, it breaks parallel build
