Correct. Please use a chroot for cross-compilation to not affect your
normal system and allow for minimal compilation e.g.:

$ mk-sbuild --target powerpc trusty

Title:
  Unable to install crossbuild-essential-powerpc on x86_64 (amd64)

Status in “build-essential” package in Ubuntu:
  Incomplete

Bug description:
  The Ubuntu 14.04LTS 64-bit is installed within a brand-new VM (using
  VirtualBox 4.3.12).  The host machine and the VM are both x86_64
  (amd64).  I would like to get a powerpc-linux-gnu cross-toolchain up
  and running, and noticed that Ubuntu had a specific package for this.

  First, I executed "sudo apt-get install build-essential".
  Second, I executed "sudo dpkg --add-architecture powerpc".
  Third, I executed "sudo apt-get install crossbuild-essential-powerpc".

  I expected the third command to succeed.  Instead, it failed while providing the following output:
  Reading package lists... Done
  Building dependency tree
  Reading state information... Done
  Some packages could not be installed. This may mean that you have
  requested an impossible situation or if you are using the unstable
  distribution that some required packages have not yet been created
  or been moved out of incoming.
  The following information may help to resolve the situation:

  The following packages have unmet dependencies:
   crossbuild-essential-powerpc : Depends: libc6-dev:powerpc but it is not installable
  E: Unable to correct problems, you have held broken packages.
