I don't think it's necessary to provide one that will DTRT. The
compiler and linker don't need that abstraction, and "install" is
only called for stuff that will be installed on the target
system.
qemu seems to have the ability to set the install command using
configure. Seems something like the following should work,
except that (1) i386-dm/hookstarget.mak uses $(INSTALL_PROG)
which seems to be defined outside of the ioemu tree, and (2) I'm
having enough trouble cross-building qemu that it's hard to test.
Thanks,
Aron
