Subject: Partially revert rC365414; `ln -n` is not portable
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=536bf3f400fdcf39651b157affdc33cca678cb1a;p=clang

Partially revert rC365414; `ln -n` is not portable

This restores the use of `rm` instead of the non-portable `ln -n`. Such
use being the status quo for the 12-month period between rC334972 and
rC365414.
