Right. So set PKG_CONFIG_PATH=/opt/arm-linux/lib/pkgconfig.
I certainly agree that'd do it. Not sure that Russell does yet, though.
That is what i currently do.
Well, I guess we were in violent agreement, then.
One caveat, though: the manpage says
PKG_CONFIG_PATH
A colon-separated (on Windows, semicolon-separated) list of directories to search for .pc files. The default directory will always be searched after searching the path;

What happens if you don't have the library in question installed in PKG_CONFIG_PATH? pkg-config will silently search /usr/lib/pkgconfig, and possibly grab the wrong version of the library.
configure.ac checks the library via pkg-config, so regardless of what library gets detected, if the autoconf check accepts the library version, the resulting build should work.

unlucky, the library will link, but the resulting program won't run. One more little reason, perhaps, to have a separate copy of pkg-config per installed userland.
If autoconf doesn't complain, the result should work. It is up to the user to make sure the right <package>.pc file is accessed by pkg-config.
