Subject: Create the clang++ symlink as a POST_BUILD custom command on clang.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=82c34603263782f9621025cc0674d8b3834cd5e1;p=clang

Create the clang++ symlink as a POST_BUILD custom command on clang.

This saves us from re-creating the symlink on every build even if we
didn't rebuild clang.
