Subject: Add an option to disable libedit
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=dc5eb2165eb2e7060104649fa19899ae5595628a;p=llvm

Add an option to disable libedit

Summary: This should provide the function similar to `--disable-libedit` with the autotools build system, which seems to be missing from the commit (r200595) that adds this.
