I am trying to compile a Debian package from source using dpkg-buildpackage.
I require the resultant binary to be Intel Pentium compatible.

I keep getting an error "Unknown Debian architecture, you must specify GNU
system type."

"i586" is not a Debian architecture (see the /usr/bin/dpkg-architecture

"i586" is not a Debian architecture (see the /usr/bin/dpkg-architecture
script.) Use "i386", and modify the debian/rules file to set compiler
options for 586 optimization, if you really need it. You might also
change the name of the package to include "586".

Would this mean that I would have to change the debian/rules file for every
package ?

I really don't want to change the source code files at this stage, since I
want to use the Debian sources as written.

Can't I set an environmental variable or change a config file, or pass a
parameter to the kernel, so that it pretends that it is a classic pentium
running at a very high speed ?

I need to frig gcc so that it only ever compiles for i586, and never
tries to detect the hardware architecture.
(I'll probably create a fork for this at some point in future.)

Some of my computers have AMD K6 or higher processors, and others have later
pentiums.

I never ever want AMD instructions, or instructions not recognized by a
classic pentium processor to appear in compiled code.

I do however want to use a full set of pentium instructions including the full
use of the match coprocessor instructions which are present on all pentium and
compatible computers.

Thanks in advance to anyone who can help.
