You mean BR2_GCC_TARGET_CPU? No, because leon3 is not set in boost.

To do minimal damage to other architectures, I would just
set it for sparc/sparc64. The boost architecture does not always
match the buildroot architecture name. (f.e. ppc is power)

I think 0003-Remove-bogus-c3-cpu-varant-for-SPARC.patch could be
removed, when a correct setting is used for sparc32.

best regards
 Waldemar
