Darwin: Correct a version check.
When the version for dsymutil comes from a clang build, it is
of the form NNmm.pp.qq where NN and mm are the major and minor
LLVM version components. We need to check for a major version
greater than or equal to 7 - so use 700 in the check.
gcc/ChangeLog:
* config/darwin.cc (darwin_override_options): Update the
clang major version value in the dsymutil check.
