I run into the problem in a similar situation, which is: cross-compiling
and deploying a full embedded Linux distro to a customizable directory
on the BUILD system, so that it can be built and then archived using
mksquashfs, but it expects to be installed to "/" on the host.
Since I have a Makefile to automate the configuring/building/installing
of all of the packages, I have the install stage install into a sandbox
directory, then I have it run a script that executes some sed magic on
the ${sandbox}/lib/*.la and ${sandbox}/lib/pkgconfig/*.pc files, and all
the other .la files in subdirectories of ${sandbox}/lib/, to properly
replace the "-L/lib/?" (regex) paths with -L${sandbox}/lib path, as well
as to force the prefix=${sandbox} in the .pc files. The install target
subsequently follows up with an:
lockf /tmp/${lockfile} rsync -a ${sandbox}/ ${deployment_dir}/
To perform the actual placement of the installed files safely in the
shared deployment directory, which would be used for building the
package.
Both the .la files and the .pc files are only of use on the BUILD
system. On the host, they won't be needed unless you plan on building
more stuff, native, on the host platform.
