Subject: doc: Remove misleading text about multilibs for IEEE long double
X-Git-Tag: upstream/12.2.0~397
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8094526109034c6c6af44de47612e97319b2c7c5;p=platform%2Fupstream%2Fgcc.git

doc: Remove misleading text about multilibs for IEEE long double

The choice of ieee or ibm long double format is orthogonal to multilibs,
as the two sets of symbols co-exist and don't need a separate multilib.

gcc/ChangeLog:

	* doc/install.texi (Configuration): Remove misleading text
	around LE PowerPC Linux multilibs.
