    Rename OSCONS_CC to GCC_FOR_ADA_RTS
    
    Several gnatlib* targets perform, with a subshell and sed, the same
    GCC_FOR_TARGET pathname transformation that OSCONS_CC performs with
    make subst macros.  Rename OSCONS_CC to a more general name, and use
    it for gnatlib as well.
    
    
    for  gcc/ada/ChangeLog
    
            * gcc-interface/Makefile.in (OSCONS_CC): Rename to...
            (GCC_FOR_ADA_RTS): ... this.  Adjust users.
            (gnatlib): Pass it down as CC.
            (gnatlib-shared-default): Likewise.
            (gnatlib-shared-win32, gnatlib-shared-darwin): Likewise.
