Aleksei Oladko 5a1292137e selftests: fix ARCH normalization to handle command-line argument
Several selftests Makefiles (e.g.  prctl, breakpoints, etc) attempt to
normalize the ARCH variable by converting x86_64 and i.86 to x86. 
However, it uses the conditional assignment operator '?='.

When ARCH is passed as a command-line argument (e.g., during an rpmbuild
process), the '?=' operator ignores the shell command and the sed
transformation.  This leads to an incorrect ARCH value being used, which
causes build failures

  # make -C tools/testing/selftests TARGETS=prctl ARCH=x86_64
  make: Entering directory '/build/tools/testing/selftests'
  make[1]: Entering directory '/build/tools/testing/selftests/prctl'
  make[1]: *** No targets.  Stop.
  make[1]: Leaving directory '/build/tools/testing/selftests/prctl'
  make: *** [Makefile:197: all] Error 2

Change the assignment to use 'override' and ':=' to ensure the
normalization logic is applied regardless of how the ARCH variable was
initially defined.
