    sparc: define SPARC_LONG_DOUBLE_TYPE_SIZE for vxworks [PR115739]

    Commit r15-1594 removed define of LONG_DOUBLE_TYPE_SIZE in
    sparc.cc, it's based on the assumption that each OS has its
    own define (see the comments in sparc.h), but it exposes an
    issue on vxworks which lacks of the define.

    We can bring back the default SPARC_LONG_DOUBLE_TYPE_SIZE to
    sparc.cc, but according to the comments in sparc.h, I think
    it's better to define this in vxworks.h.  btw, I also went
    through all the sparc supported triples, vxworks is the only
    one that misses this define.

    gcc/ChangeLog:

            * config/sparc/vxworks.h (SPARC_LONG_DOUBLE_TYPE_SIZE): New define.
