    newlib: simplify nds32 automake checks
    
    This code is a bit more convoluted than it needs to be.  GPR_SOURCES
    is never set to anything, and the automake checks use negative logic
    to add the SP & DP source files to dedicated variables that are only
    expanded once.  Get rid of the unused variable, use normal boolean
    logic, and collapse the source settings into a single variable.
