[PATCH] [SPARC] Add a workaround for the LEON3FT store-store errata

[Eric Botcazou]

> Ok, I was not aware of that policy.

The reason is that experience showed that you may have several issues for the 
same class of processors (e.g. for the original UT699) and you don't want to 
have to pass a list of -mfix-xxxx switches to fix them all.  Moreover, the 
workarounds may interact with each other (again e.g. the original UT699) so 
you don't want to have to test all the combinations of -mfix-xxxx switches.
