Could make install do a "qemu-system-x86" and then symlink the "qemu" name to
whatever the host platform happens to be? (So if you build qemu on x86-64
then qemu points to "qemu-system-x86_64"? Or if you build the sucker on a
PPC system...)
The relevant code seems to be is in Makefile.target, line 50 or so:
# system emulator name
ifdef CONFIG_SOFTMMU
ifeq ($(TARGET_ARCH), i386)
QEMU_SYSTEM=qemu$(EXESUF)
else
QEMU_SYSTEM=qemu-system-$(TARGET_ARCH2)$(EXESUF)
endif
else
QEMU_SYSTEM=qemu-fast
endif
And I have no idea what "qemu-fast" is so I'm keeping my hands off.
(Something to do with kqemu?)
I previously thought it was special casing whatever the host platform is, but
I see it's currently special casing i386 specifically.

P.S. I think the new link to be called "qemu-system-x86" rather
than "qemu-system-i386" since i386 is a specific model of x86 processor and
we haven't got qemu-system-armv4 and qemu-system-armv5, although if somebody
wanted to make a way to specify that I'd be pretty happy. (Periodically the
question comes up "how do I do a 586 build" and although it's easy enough to
cross-compile for that, it's hard to come up with a test environment without
plugging in actual hardware. "It runs on my laptop" is no guarantee, my
laptop's a Pentium M...) However, I realize there's currently a "qemu-i386"
in user emulation...
