X-Git-Tag: v6.13-rc4~6^2~2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a34e92d2e831729f0ed5df20d15b4df419cd0ba4;p=thirdparty%2Flinux.git

kbuild: deb-pkg: add debarch for ARCH=um

'make ARCH=um bindeb-pkg' shows the following warning.

  $ make ARCH=um bindeb-pkg
     [snip]
    GEN     debian

  ** ** **  WARNING  ** ** **

  Your architecture doesn't have its equivalent
  Debian userspace architecture defined!
  Falling back to the current host architecture (amd64).
  Please add support for um to ./scripts/package/mkdebian ...

This commit hard-codes i386/amd64 because UML is only supported for x86.
