Stuart Hughes,
Thank you. Several times the cross-compilation would interrupt with errors and
I could not understand why the *.la file was important to the compilation.
It was unforeseen that an innocuous statement would create cross-compilation
build and install problems.
find $RPM_BUILD_ROOT%{pfx}%{_prefix}/lib/ -name "*.la" | xargs rm -f
After removing the above statement, warnings such "file moved" and the error
"no such file or directory found" were commonplace.

Subject: Cross-compilation errors preventing build
General cross-compiling question
Are there two solutions (at minimum) to solve the following warning [file
moved] and error [no such file]? I am running into build errors. Help is
appreciated.
Error log snippet:
libtool: link: warning: library
`/home/leo/logic/Logic_BSPs/Linux_3.0/1026167_LogicPD_Linux_BSP_2.4-3/rootfs/usr/lib/libgstvideo-0.10.la'
was moved.

The following comment from StackOverflow suggests setting the dependency_libs
section.
Have you looked inside the libfreetype.la file? Libtool .la files are just text
files describing libraries. By default, they are commented. Search for the
libdir and dependency_libs settings and check if they point to the right places.
How can this be accomplished either in the configuration statement or via a
libtool -finish command?
Contents of two .la files. Note the libdir is referenced the file system
directory path under the cross-compilied target.
