    mk/config.mk.in: enable SMP on ARMv7+ (Trac #12981)
    
    Before the change result of expression
        ArchSupportsSMP="$(if $(filter $(ARM_ISA),ARMv5 ARMv6),NO,YES)"
    to evaluate to
        ArchSupportsSMP="YES"
    
    After the change it's
        ArchSupportsSMP=YES
    
    Thanks to orion for the fix!
