If that was true, you would shorten die "linux-i386" Debian architecture
with "linux" instead of "i386". In fact, it's the "linux-" or "gnu-"
which can be left, not the "i386".
Illustration for w32:
$ cat /usr/share/dpkg/ostable
[...]
w32 mingw32msvc mingw32[^-]*
$ dpkg-architecture -aw32
unknown Debian architecture w32, you must specify GNU system type, too at /usr/bin/dpkg-architecture line 234.
$ dpkg-architecture -aw32-i386
dpkg-architecture: warning: Specified GNU system type i486-mingw32msvc does not match gcc system type i486-linux-gnu.
DEB_BUILD_ARCH=i386
DEB_BUILD_ARCH_OS=linux
DEB_BUILD_ARCH_CPU=i386
DEB_BUILD_GNU_CPU=i486
DEB_BUILD_GNU_SYSTEM=linux-gnu
DEB_BUILD_GNU_TYPE=i486-linux-gnu
DEB_HOST_ARCH=w32-i386
DEB_HOST_ARCH_OS=w32
DEB_HOST_ARCH_CPU=i386
DEB_HOST_GNU_CPU=i486
DEB_HOST_GNU_SYSTEM=mingw32msvc
DEB_HOST_GNU_TYPE=i486-mingw32msvc
So, obviously, the "-i386" in "w32-i386" is necessary. As far as I can
see, dpkg-architecuture doesn't allow me to use "w32". Maybe the last
cross compiling patch for dpkg-architecure will allow me to specify
e.g. "w32" as "w32-i586", I'll have to figure that out. However,
currently there's no way to get an architecture "w32" in there.
BTW, adding "w32" to /usr/share/dpkg/archtable doesn't help, either.
But /usr/share/dpkg/archtable is obsolete, anyway.
Whatever. "w32-i586" is fine for me.
