Just passing -lexpat to the cross compiler does not lead the cross-compiler to look in /usr/lib64. The cross-compiler normally only looks in its sysroot for libraries. So there must be some -L/usr/lib64 option that tells the cross-compiler to look into this folder. > Unfortunately, the change needs to be in configure.in and AUTORECONF > fails.

What are the autoreconf issues? Can they be fixed easily? BTW, do you have a minimal defconfig to reproduce the failure? Thanks!
