Sriraman Tallam eb745e40fe Before this patch... 
Before this patch, function multiversioning determines that two functions
are different by comparing the arch type and isa flags that are set
after the target string is processed. This leads to cases where  the
versions become identical when the command-line target options are
altered.

This patch modifies the function version determination to
just compare the target string.
