Well, if you have been paying attention during the build, the Check
package, in ch6, gets installed to tools. KBD relies on some metadata from
that package. Pkg-config installed in ch10, will not search
/tools/lib64/pkg-config by default. That has to be added as a search path
for pkg-config.

Libpipeline also requires the Check test metadata from /tools/lib64,
PKG_CONFIG_PATH needs to be set again.

pkg-config's default search path for multilib is /usr/share/pkgconfig
because we have PKG_CONFIG_PATH32 and PKG_CONFIG_PATH64 for
/usr/lib/pkgconfig (32bit), and /usr/lib64/pkgconfig (64bit).
