Bug#888762: lv2.pc cannot be found during cross compilation

[Helmut Grohne]

Package: lv2-dev
Version: 1.14.0~dfsg1-1
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap
Control: affects -1 + src:yoshimi

yoshimi fails to cross build from source, because it cannot find lv2.pc.
During cross compilation, pkg-config does not search /usr/lib/pkgconfig.
One needs to move .pc files to /usr/lib/<triplet>/pkgconfig. The
attached patch minimally implements that. Please consider applying it or
passing a multiarch --libdir to waf.
