[Qemu-devel] [PATCH] Make installing bios files optional

[Riku Voipio <riku.voipio@iki.fi>]

Some distributions (such as Debian) prefer to ship BIOS
files from their respective upstream projects (openhackware,
etherboot, proll, bochbios, vgabios, ...). Or do not need it
because they just compile user emulator. However, most users
will find it convenient that known good BIOS files are shipped
together with qemu.

Introduce --disable-blobs option (default no)

Obsoletes 00_bios.patch in Debian.
