The Solaris linker fails during the build process for 64-bit builds only

since it attempts to link to both the build area version of libcairo

(object file) and the installed library at the same time (because -lcairo

shows up in various pkg-config libs and therefore is included in various

flags at link time).

Either the Solaris linker is too strict and determines duplicates in way

that is different than the GNU linker, or libtool is failing to remove the

'-lcairo' from the link line because it doesn't think it's the same library

and that is the real issue. I say this because libtool appears to remove

the '-lcairo' from the link line for 32-bit builds, but not for 64-bit

builds.
