Subject: add an escape for when targethost is not defined but usecrosscompile is.
X-Git-Tag: upstream/5.20.0~643^2~31
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=97076f2d65c868728b9943392be44a3d4c8e881d;p=platform%2Fupstream%2Fperl.git

add an escape for when targethost is not defined but usecrosscompile is.

See http://www.nntp.perl.org/group/perl.perl5.porters/2012/12/msg196443.html
"Cross-building and Makefile.SH", which explains the reasoning for this.
